What are all the planets and what are their descriptions?

Answer 1

Mercury

The planet closest to the Sun and the second smallest in the solar system. Mercury is a terrestrial or inner planet, second in density only to Earth, with a rugged, heavily-cratered surface similar in appearance to Earth's Moon. Its rotational period of 58.6 days is two-thirds of its 88-day orbital period, thus, it makes three full axial rotations every two years. Mercury's atmosphere is almost nonexistent; this fact, which produces rapid radiational cooling on its dark side, together with its proximity to the Sun, gives it a temperature range greater than any other planet in the solar system, from 466° to -184°C (870° to -300°F). Because it is so close to the Sun, Mercury is only visible shortly before sunrise or after sunset, and observation is further hindered by the fact that its light must pass obliquely through the lower atmosphere where it is distorted or filtered by dust and pollution.

Venus

Venus is the brightest object in the sky besides our Sun and the Moon. It is also known as the morning star because at sunrise it appears in the east and and evening star as it appears at sunset when it is in the west. It cannot be seen in the middle of the night.

Earth

The only known planet with liquid water and life.

Mars

The red planet. The atmosphere there is mostly carbon dioxide (96%) and only about 8% as dense as Earth's. The gravity on the Martian surface is only a little more than a third of Earth's. Mars has ice caps of frozen carbon dioxide and water at the poles.

Jupiter

The biggest planet in our solar system, with an atmosphere of hydrogen gas compressed to liquid and solid hydrogen deep within. Its "Red Spot" is a vast storm that has lasted hundreds of years.

Saturn

Has 1,000 rings, and tiny moons that orbit around them.

Uranus

The third largest planet, but less dense than Neptune. Most of its size is its thick heavy atmosphere of hydrogen and helium, but both it and Neptune have more water, methane and ammonia than do Saturn and Jupiter. Uranus is "turned on its side" with respect to its orbital axis, its "north pole" pointing in toward the Sun.

Neptune

Has a colder methane atmosphere, but (like Jupiter) an incredibly hot interior. Its rocky core is larger than Earth.

Answer 2

Mercury

The planet closest to the Sun and the second smallest in the solar system. Mercury is a terrestrial or inner planet, second in density only to Earth, with a rugged, heavily-cratered surface similar in appearance to Earth's Moon. Its rotational period of 58.6 days is two-thirds of its 88-day orbital period, thus, it makes three full axial rotations every two years. Mercury's atmosphere is almost nonexistent; this fact, which produces rapid radiational cooling on its dark side, together with its proximity to the Sun, gives it a temperature range greater than any other planet in the solar system, from 466° to -184°C (870° to -300°F).
