Venus, Saturn, Uranus, Pluto, Neptune, Mercury, Ceres, Titan, Moon, Ganymede Mars, Jupiter, Earth.

Earth, Venus, Jupiter, Mercury, and Mars have volcanoes.

Asteroids formed in the inner part of the nebula, while comets formed in the outer part of the nebula, or also known as the frost line.

Venus has the longest day of 243, it revolves the sun once every 0.615 earth years, or once every 224.7 earth days.

Earth, Venus, Mercury, Mars and 3 of Jupiter’s moons have solid, rocky surfaces and iron cores.

Jupiter, Saturn, Uranus and Neptune all have mostly hydrogen gas in their atmospheres. Venus and Mars have mostly carbon dioxide in their atmosphere.

The planets that orbit further away from the sun have less heat in their planets, with the exception of planets like Mars.

In my opinion, Mars is the planet that is most like Earth. A Martian day is just a little over 24 hours, which is very similar to ours. Its rotational axis is tilted very similarly to Earth’s rotational axis. At is said that Mars once may have had liquid water on its surface, which we have on ours right now. It is different from Earth because our moons have much different characteristics. The radius of Mars is much smaller than Earth’s radius. And the time it takes Mars to orbit around the sun is almost double of how long it takes Earth to do.
