Eddie is a crater in the
Elysium quadrangle of Mars. It is 89 km in diameter and was named after
Lindsay Eddie
Lindsay Atkins Eddie FRAS (c. 1845 – 13 October 1913) was a South-African amateur astronomer, known for his observations of Venus, Mercury and Mars and 21 comets. He was elected a fellow of the Royal Astronomical Society in 1880. He saw activ ...

Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak, as this crater has.
The peak is caused by a rebound of the crater floor following the impact. It contains material uplifted from beneath the surface.

The gravity of Mars is a natural phenomenon, due to the law of gravity, or gravitation, by which all things with mass around the planet Mars are brought towards it. It is weaker than Earth's gravity due to the planet's smaller mass. The average ...
