“This is an amazing object, given how active it is when it’s still so far from the Sun. We guessed the comet might be pretty big, but we needed the best data to confirm this,” said the paper’s lead author Man-To Hui of the Macau University of Science and Technology, Taipa, Macau.
“This comet is literally the tip of the iceberg for many thousands of comets that are too faint to see in the more distant parts of the solar system. We’ve always suspected this comet had to be big because it is so bright at such a large distance. Now we confirm it is,” said David Jewitt, a professor of planetary science and astronomy at the University of California, Los Angeles (UCLA), and co-author of the new study published in The Astrophysical Journal Letters.
