A visitor from afar
Comet C/2021 A1 (Leonard) passing close to Arcturus, the bright star in the constellation of Boötes. (06-12-21)
This comet was discovered by G. J. Leonard at the Mount Lemmon Observatory, on 3 January 2021. Orbital calculations revealed that it had spent the last 35,000 years wending its way sunward, after reaching aphelion at the chilling distance of around 3,500 AU (3,500 times the distance between our Earth and sun]. After it's closest approach to the Sun, on 3 January 2022, the comet will be ejected from our Solar System, never to return again.
On the morning of 6 December 2021, the comet was about 5 degrees from the star Arcturus. In this photo, the comet's position corresponds to 05:40 UTC+2. It was 52.5 million km away from Earth.
