: The ultimate land of extremes. Because it has virtually no atmosphere to trap heat, daytime temperatures soar to a blistering 840°F (450°C), while nights plummet to a frozen -275°F (-170°C).

: Our perfect oasis. It is the only known place in the universe to harbor life, actively recycling its crust through plate tectonics and maintaining vast oceans of liquid water.

: Earth's toxic twin. It is blanketed by a thick, heavy atmosphere of carbon dioxide that traps heat like a runaway greenhouse. This makes it the hottest planet in the solar system at a steady 900°F (475°C)—hot enough to melt lead.

Moving past the asteroid belt, we find massive worlds made mostly of hydrogen and helium gas with no true solid surfaces. About the Planets - NASA Science

These are the four planets closest to the Sun. They are made of rock and metal and have solid surfaces you could actually walk on.

: The rust-covered desert. Iron oxide (rust) in its soil gives it its signature reddish hue. It is home to Olympus Mons, a volcano three times taller than Mount Everest, and features massive dried-up riverbeds proving water once flowed there. ☁️ The Gas Giants

From metal-melting surface temperatures to sideways magnetic fields, the planets in our cosmic neighborhood are anything but boring. This guide breaks them down by their distinct groups. 🪨 The Rocky Realm (Terrestrial Planets)
