Keywords

💡Terrestrial

Terrestrial refers to a type of planet that is primarily composed of rock and metal, in contrast to gas giants which are mostly composed of hydrogen and helium. In the video, Mercury, Venus, Earth, and Mars are all described as terrestrial planets. This term helps viewers understand the composition and characteristics of these planets, which are similar to Earth in being rocky and solid.

💡Orbit

Orbit is the path that a celestial body, such as a planet, follows around another body due to gravity. The video script describes the orbits of the planets around the sun, with varying distances and periods. For example, Mercury completes an orbit in 88 days, while Neptune takes 165 Earth years. Understanding orbits is crucial to grasping the dynamics of the solar system.

💡Gravity

Gravity is the force that attracts two bodies towards each other, and it varies from planet to planet. The video provides examples of how gravity on different planets compares to Earth's gravity, affecting an individual's weight. For instance, on Mercury, gravity is 38% of Earth's gravity, which would make a 220lbs person weigh only 84lbs.

💡Atmosphere

An atmosphere is a layer of gases surrounding a planet that can affect its climate and weather. The script mentions Venus's thick atmosphere of carbon dioxide and sulfuric acid clouds, which contributes to its extreme heat. Atmospheres play a critical role in shaping the surface conditions and habitability of planets.

💡Temperature Extremes

Temperature extremes refer to the range of temperatures a planet experiences, from the hottest to the coldest. The video highlights the temperature variations on planets like Mercury, which can reach 430 degrees Celsius during the day and plummet to -180 degrees Celsius at night. These extremes illustrate the harsh conditions on some planets.

Transcripts

Today we will explore the planets in our  solar system. Thank you for watching,  

sit back and enjoy.

We will start off with the planet closest to  the sun, Mercury. Mercury is a terrestrial  

or rocky planet that orbits just under 58  million km from the sun, or 36 million miles.  

It is the smallest planet in the solar system  with a diameter of just 4,879 km. That's 3031mi.  

It is only slightly larger than earths moon,  and the two actually look quite similar.  

Despite Mercury’s small size, it is the  second most dense planet in the solar system.  

Mercury completes a full orbit around the sun  in just 88 days, yet one full day cycle on lasts  

around 58 days here on earth. The temperatures on  the surface can vary from a whopping 430 degrees  

Celsius, that's 800 degrees Fahrenheit in the day,  but with the lack of atmosphere to retain heat,  

the temperature can plummet to -180 degrees  Celsius or -290 Fahrenheit in the night.  

The gravity on mercury is roughly  38% of the gravity here on earth,  

so if you weighed 220lbs on Earth,  you would only weigh 84lbs on Mercury.  

As you can see from it’s craters, mercury has  been bartered by various impacts over the years.

Beyond mercury lies Venus.  

Venus is also a terrestrial or rocky type  planet and it orbits just over 107 million km  

or 67 million miles from the sun. It has a  diameter of 12,103 km or 7520 mi. Even though  

Venus is not the closest planet to the sun, it is  the surly the hottest with a surface temperatures  

that reach nearly 465 degrees Celsius, or  900 degrees Fahrenheit. These temperatures  

are caused by its thick atmosphere of carbon  dioxide with clouds of sulphuric acid. Venus  

covered in a thick layer of clouds which would  filter the sunlight and make the surface appear  

orange. The surface is also covered in thousands  of volcanoes, and even Mountians and valleys.  

There is a mountain on Venus called Maxwell Montes  that is similar to the size of Mount Everest.  

Venus completes a rotation around the sun in 225  days and due to its slow rotation a single day on  

Venus lasts nearly 243 days here on earth which  oddly enough is longer than a full year on Venus.  

The gravity on Venus is about 90% of earths  gravity so someone who weighs 220lbs on Earth  

would weigh about 198lbs on Venus. Interestingly  enough, it is thought that Venus was once a very  

different planet potentially even covered  in oceans of liquid water, but a runaway  

greenhouse effect occurred drastically  changing the conditions on the surface.  

It gives us a reminder here on Earth  what can occur when this happens.

Up next is a planet we are all  familiar with, our home planet,  

Earth. The earth is another terrestrial planet  which orbits the sun at a comfortable 149.6  

million kilometers or 92.9 million miles. Our  distance from the sun is a large part of what  

allows the vast diversity of life we see on  earth to thrive as well as our atmosphere.  

The Earth is the most dense planet in the solar  system and it measures in at 12,742 km across, or  

7917 miles. The temperatures can vary depending on  the time of year and your location on the planet.  

The highest air temperature ever recorded on  earth was 56.7 degrees Celsius or 134.1 degrees  

Fahrenheit. Rather fittingly, this temperature  was recorded in the Death Valley desert in furnace  

creek ranch, California in the United States.  This temperature was recorded in July of 1913.  

The lowest temperature ever recorded on Earth was  -89 degrees Celsius or -128 degrees Fahrenheit  

which was recorded at a Soviet weather  station in Antarctica in July of 1983.  

The earth completes a trip around the sun  once every 365 days it’s days last 24 hours.  

The surface has some amazing diversity  with vast frozen sections, molten sections,  

lush greenery, expansive wetlands,  

and brutally dry areas. All of  which make up our one and only home.  

I just hope we humans can adapt and better  understand how we can preserve and live off  

the lands in ways that will sustain life as we  know it rather than destroying and depleting it.

Next up is the planet commonly  known as the red planet,  

Mars. Mars is a terrestrial planet that  orbits the sun at an average distance of 228  

million kilometers, or 142 million miles and it  completes a trip around the sun in 687 earth days.  

One day on mars lasts 24.6 hours, very similar to  that of the earth. The diameter of Mars is 6779 km  

or 4212 mi making it roughly half the size of  earth. The surface is cold and dusty with an  

average temperature of -60 degrees Celsius or -80  degrees Fahrenheit, although the temperature vary  

greatly depending on location and time of year.  Temperatures have reached 20 degrees Celsius or 70  

degrees Fahrenheit near the equator. The gravity  on Mars is much lower than than that of the earth,  

it is 62% lower, so if you weighed 220lbs on  earth, you would weigh just 83lbs on mars.  

Mars is a very interesting planet  sharing many similarities with the earth,  

do you think humans will ever colonize the planet  Mars? Let me know your thoughts in the comments.

The fifth planet from the sun is also the largest,  the mighty Jupiter. Jupiter is a gas giant with a  

diameter of 139,820km or 86,880mi making it  about 11x larger than earth. Jupiter orbits  

at an average distance of 778 million kilometers  or 484 million miles from the sun, and it orbits  

the sun only once every 12 years, yet a single day  lasts just 10 hours on Earth. Being a gas giant,  

Jupiter doesn’t have a firm surface, but  it has an ocean swirling within of liquid  

metallic hydrogen deep beneath, and it lies  deep beneath the clouds. This metallic ocean is  

possible due to the immense atmospheric pressure  which keeps the hydrogen in a liquid state.  

The temperature within the clouds of  Jupiter is roughly -145 degrees Celsius  

or -234 degrees Fahrenheit, but as you venture  closer to the core temperatures may hit 24,000  

degrees Celsius or 43,000 degrees Fahrenheit  which is hotter than the surface of the sun.  

If a person who weighed 100lbs could stand  at the top of Jupiter’s clouds, they would  

feel like they weigh 240lbs with a gravity  2.4 times stronger than that of the Earth.  

But if the fell into the clouds  of Jupiter, you would be crushed  

and vaporized by the immense pressure near the  core. Jupiter is a very windy and stormy place,  

The most famous storm being the Great  Red Spot which is a hurricane like storm  

that is at lest 2 times larger than the entire  Earth, and has been raging for hundreds of years.  

The winds of this storm can  reach 423 km/h or 270 mph.  

Jupiter is an immense and deadly place for us  humans, but it is quite stunning none the less.

Next up is one of the most beautiful planets  in the solar system thanks to its mighty rings,  

Saturn. Saturn is a gas giant planet with a  diameter of 116,460 km or 72,364 mi and it orbits  

at a distance of 1.4 billion kilometers or 886  million miles from the sun, and it takes Saturn  

roughly 29 years to orbit the sun. Yet one  day lasts just under 11 hours here on Earth.  

Saturn has 3 layers of clouds and the  conditions change as you venture through them.  

The upper layers are made up of ammonia ice  and has temperatures that range from -173  

to -113 degrees Celsius or -280 to -270 degrees  Fahrenheit. The next layer contains frozen water  

at a temperature varying from -88 to -3 degrees  Celsius or -127 to -26 degrees Fahrenheit.  

Temperatures in the lower layers can reach  57 degrees Celsius or 134 degrees Fahrenheit.  

The gravity on Saturn is just 1.8  times stronger than that of the earth,  

meaning if you weigh 100lbs on earth  you would weigh 108lbs on Saturn.  

The atmosphere is made up mostly of hydrogen  and helium, but there could also be a solid core  

somewhere deep within the mighty planet. Saturn is  a breathtaking planet that is awe inspiring to see  

even through a basic telescope. I would highly  recommend it if you ever get the chance.

Next is the planet Uranus. Uranus is an  ice giant which orbits 2.9 billion km  

or 1.8 billion mi from the sun. It has  a diameter of 50,724 km or 31,518 mi.  

It takes this ice giant 84 years to orbit the sun  and has a day which lasts 17 hours here on Earth.  

Despite its frigid temperatures, The  majority of its mass comes from a hot  

dense fluid of icy materials such as water,  methane, and ammonia, meaning you would sink  

if you tried to land on the surface. The average  temperature is about -213 degrees Celsius  

or -353 degrees Fahrenheit, but as you get  closer to the planets rocky core, temperatures  

can reach 4,727 degrees Celsius or 8,540  Fahrenheit. The gravity on Uranus is about 86%  

of the earths gravity, so a person weighing 100  pounds in earth would weigh 86 pounds in Uranus.  

The atmosphere is made up mostly of hydrogen and  helium with a small amount of methane with traces  

of water and ammonia, and it is the presence of  methane which gives the planet its blueish color.

Lastly we arrive at the furthest  confirmed planet from the sun, Neptune.  

Neptune is also an ice giant which orbits the  sun at a distance of about 4.5 billion kilometers  

or 2.8 billion miles. It takes a whopping 165  Earth years for it to complete a single orbit of  

the sun and a day lasts 16 Earth hours. Neptune is  also the coldest planet in the solar system with  

temperatures that range from -218 to -200 degrees  Celsius, or -360 to -328 degrees Fahrenheit.  

Neptune is very similar to its near twin  planer Uranus with a surfaces of hot,  

dense fluid made up from icy water, methane, and  ammonia with an atmosphere of mostly hydrogen,  

and helium, as well as methane. Neptune  has a diameter of 49,244 km or 30,598 mi.  

And the surface gravity of Neptune is close to  the earths being just 1.14 times stronger. Is so  

if you weighed 100 lbs on earth, you  would weigh around 114 lbs on Neptune.  

Intense storms rage for weeks at a time  on Neptune’s surface, with fast moving  

dark vortex clouds. These storms  can grow as large as planet earth.

Our solar system gives us an interesting  look at the potential for what lies elsewhere  

in other solar systems, and beyond. It is a  great way for us to see our place as well,  

it gives a sense of appreciation just knowing  the conditions on planet earth can even support  

life at all when we see the hellish conditions  elsewhere in the solar system. That’s not to say  

there isn’t life elsewhere in the solar system,  its just yet to be discovered. But if it were  

discovered, it would be monumental and it would  be unlike any other life form we have ever seen.

I want to thank you very much for watching.
