Categories of Asteroids

➖ First, those found in the main asteroid belt, between Mars and Jupiter. This region is estimated to contain somewhere between 1.1-1.9 million asteroids.

➖ The second group is that of trojans (the name comes from Greek mythology), which are asteroids that share an orbit with a larger planet. NASA reports the presence of Jupiter, Neptune and Mars trojans.

➖ The third classification of asteroids is under Near-Earth Asteroids (NEA), which has orbits that pass close to the Earth. Those that cross the Earth’s orbit are called Earth-crossers. More than 10,000 such asteroids are known, of which over 1,400 are classified as potentially hazardous asteroids (PHAs).
