The centaur’s name classifies the icy and snowy celestial bodies in the space between Jupiter and Neptune. These Celestial bodies become active for the first time after being heated as they approach the sun.

After heating, the Centaur will dynamically transform into a comet-like appearance. Hubble used a visible light sensor to capture a snapshot of this ice body, showing that it has comet-like activity, including a tail, jet-like outgassing, and an interesting comet of dust and gas. Earlier observations by the Spitzer Space Telescope revealed the composition of the celestial body and the gas that drives its activity. Hubble researchers say that this old space telescope is the only tool that can detect active comet-like features from such a remote place in such a detailed manner.

Centaurus has a 400,000-mile-long tail, and the image shows high-resolution features near the comet nucleus, including comets and jets. Researcher Bryce Bolling said the capture of Centaur in the area was a rare event. To capture it, the celestial body must enter Jupiter’s orbit with a completely correct trajectory to have the characteristic of sharing an orbit with Jupiter.

Scientists are currently investigating how it was captured by Jupiter and eventually fell into the Trojan asteroid group. The current theory believes that this is related to a close encounter between Centaur and Jupiter. This icy object is named P/2019 LD2 (LD2) and may have passed near Jupiter about two years ago. At that time, the planet would attract alien visitors to the common orbit position of the Trojan asteroid group under the action of gravity, which is about 437 million miles from Jupiter.

This special “Centaur” star was discovered by the Asteroid Ground Impact Warning System (or ATLAS) of the University of Hawaii in early June 2019. The telescope is located in Mauna Kea and Halea. On the extinct volcano in Kara. The celestial body will not stay in the Trojan asteroid for too long. Computer simulations show that it will be in close contact with Jupiter again in about two years, when it will be ejected from the celestial system.
