According to NASA's Center for Near Earth Object Studies CNEOS), "It seems possible that the origin of life on the Earth's surface could have been first prevented by an enormous flux of impacting comets and asteroids, then a much less intense rain of comets may have deposited the very materials that allowed life to form some 3.5 - 3.8 billion years ago.". Ever since Earth formed about 4.5 billion years ago, asteroids and comets have routinely slammed into the planet. Asteroid 2018VP1 is very small, approx.

Jupiter Trojans are the most numerous, boasting nearly as high a population as the main asteroid belt. As asteroids revolve around the sun in elliptical orbits, they rotate, sometimes tumbling quite erratically. There are millions of asteroids, ranging in size from hundreds of miles to several feet across. It returned to Earth in June 2010, and the samples it recovered are currently under study. Life on Venus? This movement could have sent asteroids from the main belt raining down on the terrestrial planets, emptying and refilling the original belt. When Did the Asteroids Become Minor Planets? In the past decade, scientists have also identified a class of objects known as "main belt asteroids," small rocky objects with tails. Early on, the birth of Jupiter prevented any planetary bodies from forming in the gap between Mars and Jupiter, causing the small objects that were there to collide with each other and fragment into the asteroids seen today. ", Additional reporting by Elizabeth Howell and Nola Taylor Redd, Space.com Contributors. — NASA Asteroid Watch (@AsteroidWatch) August 23, 2020 An asteroid the size of an airplane is set to cross the Earth's orbit on Wednesday, according to NASA which expects that the space rock will not cause any harm to … All rights reserved.For reprint rights. According to CNEOS, "It has been estimated that the mineral wealth resident in the belt of asteroids between the orbits of Mars and Jupiter would be equivalent to about 100 billion dollars for every person on Earth today. PDCO would also consult with the White House and the Federal Emergency Management Agency (FEMA) and likely other space agencies, to determine what to do.
