An asteroid to happen? Asteroid cannot 'happen'. It can collide with earth, or any other object with mass, though.
Asteroids typically take thousands to millions of years to reach the Earth from the asteroid belt. Once in the Earth's vicinity, an asteroid can crash into the Earth at any time depending on its trajectory and other factors.
.72 light years
No. Adaptions usually take many generations to develop.
Ceres follows an orbit between Mars and Jupiter, within the asteroid belt, with a period of 4.6 Earth years.
It would depend entirely on how far away the asteroid was from the sun. Furthermore, which sun are you referring to? There are many suns in the solar system.
When a volcano is active it will erupt. These volcanoes might take many years to erupt but will still erupt.
The revolution of asteroids in the asteroid belt is typically between 2 to 6 years, depending on the specific asteroid's distance from the Sun and its orbital speed. The average distance of the asteroid belt from the Sun is about 2.2 to 3.3 astronomical units (AU), with one AU being the average distance between the Earth and the Sun.
It's 120 bucks Hope it helps :)
It's Rare but it can happen
It will take millions millions of years for that to happen.
If in the same area it will take all the nuteriants out of the soil and you can grow more there for many years
You could make a lightsaber,but it we'll probably take many years or it couldn't even happen.
