Takeaways

• 😀 The solar system is centered around the Sun, which is a star made up mostly of hydrogen and helium.
• 😀 The Sun is 93 million miles away from Earth and makes up more than 99% of the solar system's mass.
• 😀 The Sun's gravity keeps all the planets and other objects in the solar system in orbit.
• 😀 Mercury is the smallest planet, closest to the Sun, and has extreme temperature variations with no atmosphere.
• 😀 Venus is Earth's sister planet in size but is the hottest planet due to its thick carbon dioxide atmosphere.
• 😀 Earth is the only known planet with living things and is in the 'Goldilocks Zone,' meaning it's not too hot or cold.
• 😀 Mars, known as the 'Red Planet,' has a cold, rocky surface with water ice and two small moons.
• 😀 Jupiter is the largest planet, a gas giant with 67 moons, and is home to the Great Red Spot, a storm that has lasted for centuries.
• 😀 Saturn is known for its stunning rings made of ice and dust, and has more than 60 moons.
• 😀 Uranus and Neptune are both gas giants with methane in their atmospheres, giving them a blue color. Uranus spins sideways.
• 😀 Pluto, once considered the ninth planet, is now classified as a dwarf planet due to its small size and similar objects nearby.

Q & A

Why is the solar system called the solar system?

The solar system is called so because everything in it is centered around the Sun, and 'solar' refers to anything related to the Sun.

How far is the Sun from Earth, and why does it look small despite being the biggest object in the solar system?

The Sun is about 93 million miles away from Earth. It looks small from our perspective because of its great distance, even though it is the largest object in the solar system.

What percentage of the solar system's mass does the Sun account for?

The Sun makes up more than 99 percent of the mass in the solar system.

What is the significance of the Sun's gravity in the solar system?

The Sun's massive gravity is what keeps the planets, including Earth, and other objects in the solar system in orbit around it, preventing them from drifting into space.

Why is Venus considered Earth's sister planet?

Venus is often called Earth's sister planet because it is similar in size and gravity to Earth, but its surface conditions are extremely different.

What makes Venus the hottest planet in the solar system?

Venus is the hottest planet because of its thick atmosphere, which is mostly carbon dioxide, trapping heat through a greenhouse effect. This makes it warmer than Mercury, even though Venus is farther from the Sun.

Why is Earth called a 'Goldilocks planet'?

Earth is called a 'Goldilocks planet' because its conditions are 'just right' for life—not too hot and not too cold, with liquid water and a breathable atmosphere.

What is the significance of the two moons of Mars?

Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. Scientists believe they may be captured asteroids from the asteroid belt between Mars and Jupiter.

How does Jupiter compare in size to Earth?

Jupiter is the largest planet in the solar system. It is so large that you could line up 11 Earths across its diameter.

What are the rings of Saturn made of?

Saturn's rings are made up of countless small particles of ice, rocks, and dust. While they appear solid from a distance, they are actually composed of many tiny objects orbiting the planet.

Why is Pluto no longer considered a planet?

Pluto was reclassified as a 'dwarf planet' in 2006 because it is much smaller than the other planets and shares its orbit with other similar-sized objects in space, some of which are even larger than Pluto.

What makes Neptune's orbit unique compared to other planets?

Neptune has the longest orbit of any planet in the solar system. It takes over 164 years to complete one orbit around the Sun, meaning it was last in its current position before the American Civil War.
