Astronomers have painstakingly constructed fashions of the asteroid inhabitants, and these fashions predict that there shall be asteroids about 1 km in dimension that orbit nearer to the Solar as Venus. The issue is, nobody may discover any. Till now.
Astronomers working with the Zwicky Transitional Facility say they lastly discovered one. However this one is greater, about 2 km. If its existence may be confirmed, the asteroid inhabitants fashions might have to be up to date.
A brand new article presenting this result’s obtainable on arxiv.org, a pre-press publication web site. It’s titled "A one kilometer scale asteroid contained in the orbit of Venus." The lead creator is Dr. Wing-Huen Ip, Professor of Astronomy on the Institute of Astronomy, Nationwide Central Taiwan College.
The newly found asteroid is named 2020 AV2. 2020 AV2 has an aphelion distance of solely Zero.65 AU and is roughly 2 km in diameter. Its discovery is stunning as a result of the fashions don’t predict any asteroids on this massive orbit of Venus. This may very well be proof of a brand new asteroid inhabitants, or simply the biggest of its inhabitants.
If this discovery is simply the primary of a whole inhabitants of asteroids inside the orbit of Venus, nearly all of them will all share the identical destiny. After round 10-20 million years, they'll all be ejected.
