Astronomers have found anomalous activity on the planet “Centaurus”



make a wish

A team of scientists tracked the distant Centaurus, or a planet-like space rock, orbiting deep between Jupiter and Neptune, and finally figured out its unusual comet-like behavior.

The Centaur is particularly elusive due to its remote, highly irregular orbit. As a result, the active Centaurus-which exhibits comet-like behavior, such as producing a bright tail-is still little known because it is difficult for scientists to study them. However, according to the publication in ” Letter from Astrophysical Journal- The final decision is another matter entirely.

Split hair

The distinction between Centaurus and similar asteroids and space rocks like comets is blurry, so they are named after the mythical centaur, centaur from Greek mythology.

In this case, Centaur 201

4 OG392 appears to be sublimating carbon dioxide or ammonia-converting it directly from solid to gas-to emit a comet-like halo.

The lead research author and Northern Arizona University astronomer Colin Chandler (Colin Chandler) said in a press release: “Our paper reports on the activities generated by Centaur 2014 OG392 based on the archive images we found.” “We detect To a coma that was 400,000 kilometers away from 2014 OG392.”

look carefully

But this is a bit unusual-Centaurus usually orbits the sun so far that it is too cold to expect substantial sublimation. Therefore, now based on the discovery, 2014 OG392 was deprived of Centauri status and reclassified as Comet C/2014 OG392 (PANSTARRS).

Chandler said: “I am very happy that the Asteroid Center has awarded a new comet designation to accommodate the activities we discovered on this unusual object.”
