Outer space is full of mystery, but there are several things that we are touching the rim of, one of them being asteroids. Asteroids are rocky bodies that are smaller than that or a planet (1000 km) and larger than that of 10 cm that orbits the sun. Because of this asteroids are often referred to as minor planets or planetoids. You might wonder, what's the difference between that and a comet? Comets are icy bodies (not fiery) that leaves gassy trails, while asteroids are rocks that orbit the sun.
In the 1770’s Johann Daniel Titius, was studying the distance between planets and notice a strange occurrence. All the planets up to Mars had followed the pattern that each planet was about 1.5 times further out than the previous planet. But between Mars and Jupiter, the pattern broke. Sought to discover the missing planets, scientists begin to scout the solar system and found our first asteroid in 1801, Ceres. It wasn't until the discoveries of another 3 asteroids (2 Pallas, 1802; 3 Juno, 1804; 4 Vesta, 1807) that scientists realized that they've discovered something other than planets.
After discovering and 4 Vesta there was a stoppage in the findings of asteroids until 1845. But since then discoveries had grown in huge amounts. In 1857, 50 were discovered, by 1900, 463 were discovered, and by present day roughly 376,537 have been discovered. Out of the 376,537 asteroids, 159,366 have orbits well known enough to have numbers but only 13,805 have names.
A few notable asteroids are:
- Ceres: largest and first asteroid discovered
- Pallas: second largest and discovered asteroid
- Juno: tenth largest asteroid, third discovered, also first asteroid where an occultation was observed (1958)
- Vesta: third largest asteroid, 4th one to be discovered.
