The average temperature of an asteroid is -100 degrees Fahrenheit. Asteroids are also known as minor planets that typically revolve around the sun.
The small, rock-like masses were first discovered by Giuseppe Piazzi in 1801. The discovery was accidental, but it paved the way for scientists to study these unique structures. Asteroids can reach an extremely large size, one named Ceres totaling a massive 583 miles across. Some are rather small as well and can be less than 20 feet across. The asteroid revolves elliptically and some even have companion moons. The majority of asteroids revolve around Mars and Jupiter. Asteroids also have the potential to slam into Earth. According to NASA, large asteroid strikes are very rare, and they can be detected beforehand.
