Astronomy for ALL

Announced on July 23, 2015, planet Kepler-452b is larger than Earth and orbits a star nearly identical to the sun, but older and therefore hotter. The planet's orbit is nearly the same as Earth's, and its year is about 20 days longer than Earth's. Kepler-452b is 1,400 light-years away.

Mars takes its name from the Roman god of war:
The ancient Greeks called the planet Ares, after their god of war; the Romans then did likewise, associating the planet’s blood-red colour with Mars, their own god of war. Interestingly, other ancient cultures also focused on colour – to China’s astronomers it was ‘the fire star’, whilst Egyptian priests called on ‘Her Desher’, or ‘the red one’. The red colour Mars is known for is due to the rock and dust covering its surface being rich in iron.
