Answer 2

Because of its distinctive rusty hue, Mars is commonly referred to as the Red Planet. Even from Earth, the color of the planet may be seen with the naked eye; it appears in the night sky as a red star.

Explanation:

• Particles of iron oxide are all over Mars' surface. Rust gets its red hue from iron oxide, the same substance.
• Due to its smaller size and lesser gravity compared to Earth, Mars has an abundance of iron oxide on its surface.
• The planets' surfaces would have been formed of infernal lakes of molten rock and metals, including naturally occurring iron oxide, when they were forming some four billion years ago.
