Solar System - Uranus. Uranus, the third largest planet in our solar system, may be the strangest because it spins on its side. That severe tilt to its rotational axis may result from a great collision long ago.

Planetary surface temperatures tend to get colder the farther a planet is from the Sun. Venus is the exception, as its proximity to the Sun, and its dense atmosphere make it our solar system's hottest planet.


Which is smaller than Pluto?

9. The dwarf planet Eris —once thought to be the largest body in the solar system beyond Neptune's orbit— may actually be smaller than Pluto, new observations suggest.

Is Pluto still a planet?

What color is Mars?

Mars, known as the Red Planet, is a mostly dry and dusty place. A variety of colors can be seen on the surface, including the predominant rusty red the planet is known for. This rusty red color is iron oxide, just like the rust that forms here on Earth when iron oxidizes – often in the presence of water.

Meet what may be the largest carnival delights known to science: the “super-puff” worlds of the Kepler 51 star system. As their confectionary name suggests, these planets are as lightweight as cotton candy—literally. The fluffy globes are the lowest density exoplanets ever discovered beyond Earth's solar system.

How big is the Pink planet?

This planet, GJ 504b, is about the size of Jupiter, but has several times its mass. It's actually so far the smallest planet that's ever been directly imaged with a telescope, rather than being observed by eclipsing its parent star.
