Takeaways

😀 Planets are celestial bodies that orbit a star, such as the Sun, in a specific elliptical path at certain speeds.
😀 An orbit is the elliptical path a planet follows around the Sun.
😀 Mercury is the smallest planet in the Solar System and the closest to the Sun.
😀 Mercury has no natural satellites and lacks a significant atmosphere.
😀 Mercury experiences extreme temperature fluctuations, with daytime temperatures reaching 430°C and nighttime temperatures dropping to -183°C.
😀 Mercury's rotation takes 58.25 days, while its revolution around the Sun takes 88 days.
😀 Venus is the hottest planet in the Solar System, with surface temperatures ranging from 450°C to 475°C.
😀 Venus has no natural satellites and its atmosphere is made up of 96% carbon dioxide.
😀 Venus rotates clockwise (from east to west), which is unique among the planets.
😀 Earth is the only planet in the Solar System known to support life, with its atmosphere protecting it from radiation and meteor impacts.

Q & A

What is a planet?
-A planet is a celestial body that orbits a star (like the Sun) along a specific path with a certain speed.
What is an orbit?
-An orbit is the path a planet follows as it revolves around the Sun, and it is typically elliptical (oval-shaped).
What are the key characteristics of Mercury?
-Mercury is the smallest planet in the solar system, the closest to the Sun, has no moons, no atmosphere, and experiences extreme temperatures, ranging from 430°C in the daytime to 183°C at night.
How long does it take for Mercury to rotate on its axis?
-Mercury takes approximately 58.25 days to complete one rotation on its axis.
What is the orbital period of Mercury?
-Mercury takes 88 days to complete one orbit around the Sun.
What are the key characteristics of Venus?
-Venus is the hottest planet in the solar system, with temperatures ranging between 450°C and 475°C. It has no moons, an atmosphere mostly composed of carbon dioxide, and rotates clockwise (from east to west).
Why is Venus sometimes called the 'Morning Star' or 'Evening Star'?
-Venus is called the 'Morning Star' because it is visible just before sunrise, and the 'Evening Star' because it can also be seen after sunset.
How long does Venus take to complete one rotation and revolution?
-Venus takes 243 days to rotate on its axis, while it takes 225 days to complete one revolution around the Sun.
What are the key characteristics of Earth?
-Earth is the only planet in the solar system known to support life. It is covered by an atmosphere that protects from harmful solar radiation and meteors, and about two-thirds of Earth’s surface is covered by water.
How long does it take for Earth to rotate and revolve around the Sun?
-Earth takes 24 hours (1 day) to complete one rotation on its axis and approximately 365.25 days (1 year) to complete one orbit around the Sun.
How many moons does Earth have?
-Earth has one natural satellite, which is the Moon.
Why does Mercury experience such extreme temperatures?
-Mercury experiences extreme temperatures because it has no atmosphere to regulate heat. During the day, it is scorched by the Sun, and at night, the heat escapes rapidly into space.
