The fastest meteorite discovery in the solar system
WASHINGTON, DC: Astronomers at the Carnegie Institution of Science have discovered the fastest meteorite (asteroid) in our solar system that completes one revolution around the sun in just 113 days.
It should be noted that the planet Mercury completes one orbit around the Sun in less time, ie in just 88 days, however, firstly it is a planet and secondly its orbit is very stable.
In contrast, the newly discovered astronomical body is a meteorite with a very irregular or elliptical orbit.
As a result, it travels in its orbit at a distance of only 20 million kilometers from the Sun. This distance is less than the average distance of Mercury from the Sun (47 million km).
On the other hand, at its extreme distance from the Sun, its distance (from the Sun) is more than 110 million kilometers, which is more than the orbit of the planet Venus (Venus).
The meteorite, about one kilometer in size, has been discovered by Scott Shepard and his colleagues, who have named it “2021 PH27”.
He added that when it passes very close to the sun, not only does it accelerate, but its surface also becomes extremely hot and its temperature is around 500 degrees Celsius. Arrives
The discovery of “2021 pH27” has been confirmed with the help of several powerful binoculars.
Given its bizarre orbit, astronomers say it may have occurred in the “asteroid belt” millions of years ago. (This belt of countless small and large meteors is located between Mars and Jupiter.)
However, for some reason its orbit was affected and it changed its course.
Its current orbit is also very unstable, so it is very possible that in the next few million years it will collide with Venus, Mercury or the Sun and end its existence forever. Or go into a completely different orbit than your current orbit.
Scott Shepherd says that the discovery of such strange celestial bodies will help us to understand the origin and evolution of meteors and comets and will be able to better understand our own solar system. ۔
