Comet Leonard 2021: How and when can we see this recently discovered comet? - MARCA.com

Until December 13, the comet will be visible in the morning sky with binoculars or a telescope.

About 35,000 years ago, when the first cave paintings appeared and the time of the Neanderthals was coming to an end, Comet Leonard was at aphelion (the point in its orbit farthest from the Sun), some 525 billion kilometers away (about 3,500 times the distance separating the Earth from the Sun).

This December, the comet's long journey into the inner Solar System will have its closest approach to Earth, and it will be possible to observe it in the night sky.
