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, The comet Leonard (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 comet With the nickname of many Terrans ” Evening star After sunset. However, we have to wait until the flashing lights Twilight Goes out a little for a chance to discover the brightest comet of the year. These days she is at her peak Brightness (Viewed from Earth), around Size +4. VisibleEye No.Star Much Spreads Express yourself more easily and beautifully with a telescope or a pair of telescopes. Telescope If you have one.

Where is the comet Leonard?

It’s not so hard to find, it goes down to the brightest star in the sky – then நிலா And the sun -, Friday Of course (size -4.6).

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 small Constellation From Microscope. 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 சோலைல் January 3, 2022, perihelion date, point Around the circular path 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 Solar System.

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 edge of the solar system, 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 Friday 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.Astronomer 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 Remember 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”! “.

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. Light (Telescope or refracting telescope), if you have one (or know someone who owns one). After that you can enjoy the beauty of its centerpiece Gas, Its hair and long tail extending between the planets facing the sun.

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 Milky Way. But you should look for it in the twilight lights just below the southwest horizon.
