A 4-billion-year-old comet is approaching the sun

NASA and astronomy at the University of California, America, are monitoring the largest comet ever discovered, 4 billion years old, approaching the sun for more than a million years, traveling at a speed of 35,405.57 kilometers, and a width of about 140 kilometers.

Astronomers used the Hubble Space Telescope to confirm the solid center of the giant comet C/2014 UN271.

“Comets, among the oldest objects in the solar system, are icy bodies that have been unceremoniously tossed out of the solar system in a game of pinball and gravity between massive exoplanets,” said David Jewett.

This comet contains the largest nucleus that astronomers have never seen in a comet.
