In olden times. people trembled with fear when they saw a comet. They believed that comets were evil signs foretelling plagues, wars, and doth. Of course, we no longer believe this, but some people still wonder if a comet could cause harm on earth. Suppose a comet explodes?
As far as we know, comets do not explode. But they do break up. For example, there was a certain comet that had been observed several times, and then in 1846, it split in two, making a pair of comets. Finally, both parts broke up into bits too small to be seen. These pieces are thought to be the shower or meteors that we see regu1arly’in late Novem- ber. So it would seem that comets do eventually die. They do this by breaking up and then scattering along their orbits in the form of meteoric dust.
A comet is not a solid chunk of matter. Scientists think that comets are roade of great swarms of bits of solid matter combined with gases. The brightest part of a comet is “the head”. The center of the head is made of the heaviest material and is called “the nucleus”. Around the nucleus is a part known as “the coma”. It is a hazy, cloudlike cover that may 150,0iXi or more across. And the tail of a comet is made up of very thin gases and fine particles.
So even though a comet looks pretty solid when it glows across the sky, it is really mostly tiny particles and gases.
What Happens If A Comet Hits Earth?
A PLANET-busting comet could crash into the Earth and wipe out humanity in less than six months .
Will a comet ever hit Earth?
Today, we’ll answer a question about the sky, and how a comet will impact Earth in the future. A comet is a small icy world orbiting the sun, which can be up to millions of miles away from the sun. In fact, the last time a comet hit Earth was around 66 million years ago, and it caused an extinction event that wiped out half of all life on the planet. Currently, we have no idea whether a comet will hit Earth, but we do know that this time, we will have a much better warning.
Is a comet coming in 2022?
Comets are relatively uncommon in our solar system, but it’s not completely unheard of for one to make an appearance. When one does, it’s usually fairly spectacular, like the one that recently made a pass by the Sun. However, that’s not what we’re going to talk about today. Instead, we’re going to investigate the annual comet that will make its closest approach to Earth in June 2022. The comet, which will officially come to be known as “Halley’s Comet“, is named after the late English astronomer Edmond Halley. Halley’s comet is believed to originate from the Oort Cloud, a sparse region of icy objects that circle the solar system, approximately 100,000 AU away from the sun.
How fast do comets travel?
about 2,000 miles per hour
When was the last Comet seen
The last time we saw a comet was in 1987, on the morning of April 16. That morning, the comet was shining brightly in the eastern sky, just south of the Big Dipper. For the next few days, the comet shone every night in the eastern sky, then disappeared completely over the summer.
