12, Comet Leonard – nicknamed the “once in a lifetime” comet – passes close to Earth, shrouded in a green glow.

Leonard or Comet C/2021 A1 will approach Earth in about 35,000 years, named after astronomer Gregory J. Leonard, who discovered it in January 2021. Although it is expected to be closer to our planet on December 12, the comet will be visible. Throughout the month.

Hey Leonardovy

Leonard is a long-lived comet from the far reaches of the solar system. At its farthest from the Sun, the indifference distance extends to 3700 AU (1 AU is the average distance between the Earth and the Sun).

Its orbital period is 80,000 years. But that will change soon.

According to current calculations, the comet will be ejected from the solar system after passing through the sun, heading into interstellar space and not return. It will likely pass through another star system light years away, just as the interstellar bodies 1I/’Oumuamua and 2I/’Borisov recently passed through our solar system.

The comet, which was located around the core of NGC 4631 (then known as the Whale Galaxy), was seen by Gregory Leonard in images taken from the Mount Lemon Observatory in Arizona. The discovery occurred in January 2021, just one year before the closest approach of the sun was expected on January 3, 2022.

When and Where Can You Catch Comet Leonard?

The best time to catch a Leonard would be early in the morning, a few hours before sunrise. You will be at the highest point in the sky just before dawn.

In the first weeks of December, Leonard can be seen in the eastern and northeastern quadrants of the sky. As it approaches Earth, Comet Arcturus will pass between the brightest star in the constellation Bootes and the handle of the Big Dipper asteroid.

It should be noted that since it will pass through several constellations over several days, if you take an hour or two to observe the comet, you can see it against the stars in the background during one session. They will see you walk.

The comet will be visible in the evening sky after sunset on December 14. And while Comet Leonard will be closest to Earth on December 12, astronomers believe that December 17 will be the best day to observe it.

Is Comet Leonard Easy to See?

This is an interesting question because, as comets walk, it is known that the class to which Leonard belongs is unpredictable in terms of vision. However, due to the visibility of this particular comet, experts believe that Leonard can be seen with the naked eye. However, it is advisable to carry binoculars or binoculars.

For those who cannot watch this cosmic performance in person, live viewing is set to take place on the night of December 11th. The Virtual Telescope Project in Rome, Italy will host a free online observation of this comet starting at 11:15 CST. (December 12 10:45 a.m.). See while browsing for more information You areAnd
