Mercury: The Closest Planet

Katie Shen

Mercury Information• Mercury is one of the terrestrial planets, which means

that it has a rocky surface. • It is 0.39 AU or 58 million kilometers from the Sun. It is

the closest planet to the Sun, so the planet experiences extreme temperature throughout its day.

• It is hard to view from Earth, because its solar radiation damages telescope optics.

• It is not a likely place to find life because it has almost no atmosphere and no water.

• Mercury contains far more metals than the other planet in this solar system. It also has a magnetic field.

• The methane gives the planet its blue color.• Uranus is 19 AU from the sun, or 1 billion, 780

miles from the sun.• Uranus’ axis has a 97.86 degree tilt. Therefore

Uranus is also known as ‘the tilted planet’.• A day on Uranus is around 17 hours.

The methane gas on Uranus gives it its bluish color.
