There are comets around all the time. In order to have this much of a cataclysmic effect, it would need to pass very close to the earth, if not hit it entirely. At the moment, we do not know of any comets on this trajectory.
No. The only way a comet could cause a catastrophe would be if it collided with Earth. The orbit of Halley's Comet keeps it at a safe distance from us.
In 1986, the Giotto spacecraft flew within 400 miles of the nucleus of Halley's Comet. This close encounter provided valuable data and images of the comet's nucleus and helped scientists learn more about these cosmic objects.
Not directly, but as a comet approaches the sun, which is one big fusion reactor, the heat will cause the surface of the comet to vaporize, forming the comet's tail.
cause it gets to close to the sun
When it is from very far away, nothing. But when a comet approaches the inner Solar System,solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. That is what we call the 'tail' of a comet.
When a comet nears the sun, and begins to out-gas, solar wind pushes the particles away. as the comet nears the sun, more & more particles are emitted, and the tail grows.
Comets rarely cause damage to Earth as they are small icy bodies that burn up in the atmosphere or pass by harmlessly. However, if a large comet were to impact Earth, it could cause catastrophic damage due to the high speed and energy of the impact.
A shooting star, which is within the Earth's atmosphere.
The Milky Way is neither a planet nor a comet. It is a spiral galaxy that contains our solar system and billions of stars, along with gas, dust, and dark matter. It is not a single object within our solar system like a planet or a comet.
The tail of a comet always points away from the Sun, no matter which direction the comet is moving. This is because the Sun heats the comet up and blasts away the 'dirty ice' it's composed of, creating a tail that streams away from the Sun.This means that a comet can actually be travelling such that it's tail is ahead of it.
