Scientists have discovered an asteroid unusually close to the Sun, almost always closer than the second planet in the solar system of Venus.
This asteroid was named 2019 AQ3. Its elliptical orbit is not only closer to the Sun than that of Venus, but it also periodically approaches daylight even closer than
Mercury This is reported by Science Alert.
A tour of the Sun, this asteroid only takes 165 days. This is the shortest year that can be observed on one of the asteroids of the solar system.
The year on Mercury lasts 88 days, on Venus – 225 days, on Earth – 365 days.
The discovery of this asteroid is very important because it can testify to the presence of other similar objects in a part of the solar system apparently already well studied.
The asteroid was first noticed on January 4, 2019 in the Zwicky Transient Facility (ZTF), an automated sky monitoring project led by the California Institute of Technology Observatory.
on Mount Palomar (San Diego, CA). Soon, its unusual nature became clear to other astronomers and, on January 6 and 7, some
telescopes
In addition, in the Pan-STARRS 1 telescope archives of the Haleakal Observatory in Hawaii, previously untested evidence of an asteroid, dating from 2015, was discovered.
From archival data and new observations, the researchers were able to accurately calculate the AQ3 orbit of 2019. It moves in a strange cycle that moves it higher and lower
orbital plane of the solar system. This is rather unusual, as most of our star systems, located in the Oort cloud, adhere coherently to the orbital plane.
The proximity to the Sun is also unique: its proximity to the Sun is unique: only 19 (including 2019 AQ3) of all the huge asteroids of the system solar whose orbits are completely
are in the orbit of the Earth. These spatial objects are called Atira's astiros. Although they are not threatening at the moment, this could change in the future, if any.
The orbits will be modified by the influence of Venus or Mercury.
In addition, the size of the QQ3 of 2019 is quite large, it is estimated at about 1.6 km.
"This is one of the largest asteroids whose orbits are completely in Earth's orbit, a very rare case," notes Californian Technical scientist Coyangji.
l & # 39; institute. "In many ways, the AQ3 2019 is really a strange asteroid."
Recall that at the end of December, near the Earth, a potentially dangerous flight was a dangerous asteroid that looked like a hippopotamus.
