Comet Leonardo: Will ‘brush’ the earth and see with the naked eye this weekend

Comet C / 2021A1, named It was invented by Leonardo, Gregory J. Leonard, Can be found at South America By mid-December, between 12 and 14, it will be very close to Earth.

Leonardo Comet will be seen on any given day

Because the dust and gas it emits are unpredictable, scientists have not been able to establish an exact date for when it will peak. As reported in the NASA record.

“At that time – it is likely to be bright enough to be seen with the naked eye, but comets you do not know, unfortunately,” say experts in the agency article.

According to astronomers, in the first two weeks of December, the comet Leonard will be east of the horizon just before sunrise. In those days it will be bright, so it will be hard to notice.

How Leonardo’s comet was discovered

Leonardo was diagnosed For the first time at Mount Lemon Observatory, Located January 3 in Arizona. At the time, it had a faint glow of magnitude 19, 160 thousand times fainter than low-brightness stars visible without a telescope.

Gregory discovered it when there were five astronomical units from the Sun near Jupiter. An astronomical unit represents an average distance of 149.565 million kilometers between the Earth and the Sun.

comet It travels in a very long flat elliptical curve, forming its largest distance from the Sun at 3,500 astronomical units – 523 billion kilometers.

As the comet travels in a closed orbit, it may have moved closer to the Sun about 70,000 years ago. This means that its surface is covered by highly volatile substances such as nitrogen, carbon monoxide or carbon dioxide. The ice evaporates from the sun, which produces more brightness in the comet, and the brightness fades as it approaches.
