Today, this year’s brightest comet, Leonard, moves as close to Venus as possible, shining at dusk. An event not to be missed this weekend! A comet never went very close to our neighbor in human memory.
After passing close to Earth – 35 million kilometers anyway – last Sunday, TheLeonard (C / 2021 A1) is closest to Venus today. It grazes at a distance of about 4.2 million kilometers. If we were on Venus and her sky was clear, we would be surprised to see that scene.

Anyway, when viewed from Earth, this is pretty much it: roughly we can see With the nickname of many Terrans ” After sunset. However, we have to wait until the flashing lights Goes out a little for a chance to discover the brightest comet of the year. These days she is at her peak (Viewed from Earth), around +4. Visible No. Much Express yourself more easily and beautifully with a telescope or a pair of telescopes. If you have one.
Where is the comet Leonard?
Tonight, December 17, C / 2021 A1 (Leonard) will be southwest, low on the horizon (see clear location to see it).
On December 18, the comet Leonard will still be near Venus, but to its left, at 7 a.m. east (see picture above) from the brightest star. The comet is still clearly visible.
On December 19, C / 2021 A1 (Leonard) continues to take off, overtaking Venus in the sky. Still in Sagittarius, she will soon enter smallFrom . As the terrain slides more and more over the horizon, its visibility becomes harder.
Very fast, the comet will remain dark for the next two weeks January 3, 2022, perihelion date, point Very close to our star. It is exactly one year since Gregory Leonard was discovered. Then it will be much harder to notice. As for seeing her again, it all means that it will never be possible again, because she will be expelled from us. .
The comet Leonard will be visible in the evening, and this will be the last time we see it

Comet Leonard: Remember its name, because it will be spoken until December and the beginning of 2022. Discovered a year ago, it promises to be the comet of the year! How, when and where should this be noticed?
C / 2021 A1 (Leonard), or more simply, the comet Leonard, looks very promising to be seen with the naked eye in the days to come. Came from , The star is now orbiting near and (almost) the dual planets Earth and Venus.
Its smallest distance with our planet is this Sunday, December 12 at 1:52 pm UT precisely at 2:52 pm Paris time, when it was about 35 million kilometers away, so there is no danger to us. , Terrence. A few days later, on December 17-18, it will return Welcome it to its surroundings and touch it this time because it will only cross four million kilometers from its surface! We did not dare to imagine the view from there.
Comets are like cats, both have tails and both do what they want
Then, the comet will continue in its path to Perihelion, the point of its orbit closest to the Sun, which was discovered on January 3, 2022, exactly one year later. Goes beyond how unpredictable comets are: “A brilliant and famous comet inventor once said: ‘Comets are like cats, they both have tails and both do what they want”! “.Gregory J. Leonard – who naturally gave it its name – at the Mount Lemon Laboratory. C / 2021 A1 will travel 92 million kilometers from our star (i.e. 60% of the distance between the Earth and the Sun), which is a lot, so it reduces the risk of decay. Although it is not ruled out that this will happen; It naturally depends on the combination of snow and dust at its center. When a comet passes through the hottest part of the solar system it is always at high risk of breaking. We hope this does not happen so that one can make the best use of the view of the sky in the morning and later in the evening. Because this will be the last time it passes here: because of its speed, researchers believe it will be ejected from our solar system in a few thousand years. “This is the last time I see her” Gregory Leonard promises (researcher Lunar and Planetary Laboratory From the University of Arizona), which
Where is the comet Leonard?
Experts predict that the comet Leonard will be below size 6 (below the visible range of a star) for several days, and may flirt with size 4 as it moves as close as possible to Earth. Everything indicates that its brightness will peak between December 11 and 13 (when viewed from Earth, always). However, is it clear in the sky? The answer is yes under certain conditions because it will soon disappear from the morning sky and emerge in the evening one. Because a star is so pervasive – not at the right time as a star or a planet – it is not easy to distinguish it with the naked eye. To do this, it is important to know your situation well and to double your focus. To maximize the chances of admiring it, it is strongly recommended to bring a pair of telescopes or more collectors.(Telescope or refracting telescope), if you have one (or know someone who owns one). After that you can enjoy the beauty of its centerpiece , Its hair and long tail extending between the planets facing the sun.
For weeks now, the comet has been followed by many amateur astronomers around the worldPhotos of their hunt. Among the most beautiful and spectacular is the C / 2021 A1 front display , Located in the background, millions Of the earth. Most recently, on December 3, the comet Leonard approached Messier 3 ( ) Apparently of course, because M3 is actually 35,000 light years away from us, and the comet.
The Leonard comet is visible at dusk
In early December, the comet Leonard appears high in the sky in the second half of the night, Passes de Chasse au Bouvier, southeast. Its high velocity (254,000 km / h) transcends the celestial body (which seems to us to be stable) with much improvement compared to “fixed” stars. At night, the star loses altitude in the sky and approaches the horizon as it advances towards Earth. On December 9, he entered the constellation of Serpentarius and will soon disappear from the morning sky (dawn on December 13) to slide into the evening sky on December 14. Then she will be in front . But you should look for it in the twilight lights just below the southwest horizon.
On the evening of December 16, you can enjoy it in front of Sagittarius. On December 17th and 18th, near the glow . Opportunity to remember these beautiful garlands With will be enhanced by the alignment of our neighbors And . Also included , The most beautiful meteor shower of the year, whose peak activity coincides with the night of the comet’s shortest distance from Earth.
So, I can not recommend enough of you to go out and enjoy these beautiful sky shows in the heart of the longest nights of the year. By turning , To enjoy all the stuff that fills the darkness. Comet Leonard will undoubtedly be the comet of the year, and if its brightness continues to increase as advertised, you will have to wait 35,000 years to see it again if you miss it (according to its estimates). ), As always, at
