";s:4:"text";s:3086:"Astronomers think that the asteroid belt is made up of material that was never able to form into a planet, or of the remains of a planet which broke apart a very long time ago. I asked this question a couple of days ago and got back two answers claiming the asteroid belt is anywheres from 2.4 to 10 AU's across. NO. The asteroid belt is situated between the orbits of Mars and Jupiter around 280 million miles (450 million km) from the sun. There are more than a half-million known asteroids, most of which are found in … This asteroid is about 315 km (195 miles) in diameter with a mass of 3.27×1019 kg. Learn vocabulary, terms, and more with flashcards, games, and other study tools. If all the asteroids were combined together, their diameter would be about 1,300-1,500 kilometers across, less than 1/2 the diameter of the Moon. The average distance between objects in the Asteroid Belt is quite large.
It doesn't really list the entire thing but it mentions it as though they were combined together. If all the asteroids were combined together, their diameter would be about 1,300-1,500 kilometers across, less than 1/2 the diameter of the Moon. It is believed asteroids are the remnants from the formation of the planets.
That places it between 2.2 and 3.2 astronomical units (AU) from the Sun. As mentioned above, the entire mass of the Asteroid Belt is estimated to be somewhere around 2.39 X 10 21 kg, accounting for only 4% of Earth’s moon mass. Scientists estimate the asteroid belt also contains between 1.1 million and 1.9 million asteroids larger than 1 km (3,281 feet) in diameter and millions of smaller ones. Some asteroids in the Belt are quite large, but most range in size down to pebbles. Asteroid, also called minor planet or planetoid, any of a host of small bodies, about 1,000 km (600 miles) or less in diameter, that orbit the Sun primarily between the orbits of Mars and Jupiter in a nearly flat ring called the asteroid belt. Asteroid Belt Facts Between the orbits of Mars and Jupiter, the asteroid belt contains an estimated 1.9 asteroids. This means that the asteroid and the planet follow the same path around the sun. I REALLY DONT KNOW The asteroid belt probably contains millions of asteroids. I meant the diameter of the cross section of the orbital path. NASA found 861 asteroids measuring more than 0.6 miles across. Most asteroids in our solar system can be found in the asteroid belt, between Mars and Jupiter. This main asteroid belt holds more than 200 asteroids larger than 60 miles (100 km) in diameter. Search. and 3.6 U.A, a ring 225 million kilometers wide and just as often .. 52 Europa — is an asteroid located within the asteroid belt.
The last near-Earth asteroid count was performed in 2013.
