Io, moon of Jespiter Jupiter, is famously volcanically active. It has more than 400 active volcanoes, over an area the size of Asia. Some of the volcanic mountains are taller than Mount Everest.
With more moon missions on the horizon, avoiding crowding and collisions will be a growing challenge
Interest in the moon has been high – just in the past two years there have been 12 attempts to send missions to the moon, ...
Characteristics: Quasi-moons can range in size from 30 feet to 1,000 feet. They experience gravitational tugs from Earth, allowing them to slide in and out of shared orbits. Discovery: Astronomers ...
