The appearance of a rare asteroid in orbit closer to the Sun than Venus

We have always looked at the sky and studied the solar system, and as science progressed, we know to a great extent how things are going. But a new discovery suggests the presence of rarer asteroids that we do not know, says Michel Starr on the Science Alert website.

The discovery involved an asteroid named 2019 AQ3Its narrow elliptical orbit is almost as close to the sun as Venus and only takes about 165 days to circulate around the sun, the shortest year of the solar asteroid system.

"We have discovered something unusual that has almost no orbits beyond that of Venus and there could be a lot of unknown asteroids," said Michel to space scientist Quanzi Ye of California center for analysis and infrared therapy.

Yi had originally observed the asteroid on January 4, 2019 in the transit facility data of Zoeke, known as "ZTF), An automatic antenna study project managed by the Palomar Observatory in Caltech. The asteroid did not take long to prove to be of an unusual nature and many telescopes were published for study on January 6 and 7.

The archives of the telescope have been shown Pan-STARRS 1 At the Halikala Observatory in Hawaii, unanticipated evidence on the asteroid dates back to 2015. Based on archival data and a new meteorology, the researchers were able to accurately calculate the orbit . AQ3 From 2019, it turns out to be walking in a strange loop that takes it above and below the orbital level of the solar system.

The proximity of this asteroid of the sun is strange. Of all the asteroids in the solar system, only 19 are asteroids (including 2019) AQ3) Whose orbits are entirely contained in the Earth's orbit. These asteroids are known as Atira Atira, Or Abohil Apohele, Or internal objects of the EarthGOOSEAlthough this is not a threat at the moment, it could change in the future if its orbits are affected by the orbits of Venus or Mercury.

The new size of the asteroid increases its size, so we do not know a lot of asteroids of a size close to its size. Although it is now impossible to determine the exact dimensions of the asteroid on the basis of limited observations to date, current estimates suggest that it is up to 1.6 kilometers (1 mile). "It's one of the largest asteroids whose orbit is entirely orbiting the Earth and it's a very rare species," said Michelle to Ye.
