The Chicxulub asteroid impact, which occurred about 66 million years ago, is believed to have played a significant role in the mass extinction event that wiped out the dinosaurs. However, the formation of Earth itself occurred much earlier, around 4.5 billion years ago. After the impact, the planet underwent significant geological and ecological changes, leading to the eventual rise of new species and ecosystems over millions of years. Thus, the Earth was already formed long before the Chicxulub event, but recovery and evolution following the impact took tens of millions of years.

What is chicxulub?
Chicxulub is a town located in the Yucatán Peninsula in Mexico. It is also the name of the impact crater buried beneath the town, which was formed by the asteroid impact that is widely believed to have caused the extinction of the dinosaurs around 66 million years ago.
Can you see comets all year long?
Yes, as long as an asteroid is within visible distance of earth.
Itmay have crashed into earth and caused a mass extinction a long time ago?

What if a 1000 km long astriod hit the earth?
The general hypothesis is that we will all die. Any remaining humans would have to revert back to a primordial existence.A 1,000 kilometers, is the distance from Washington NY to Chicago.The Chicxulub extintion asteroid, which wiped out 99% of life on Earth was a mere 10km.
What asteroid is 21 miles long and approaches as close as 75 light seconds from earth?

Why would scientists want to know if an asteroid is on a course to collide with earth in 20 years?
If an asteroid were to hit Earth, it could do HUGE damage. It was the changes to Earth after an asteroid hit that killed off the dinosaurs. But if we knew about an asteroid heading our way long enough ahead of time, maybe we could change it's course enough to make it miss, and save millions of lives.

How long before the metor as big as Texas will hit earth?
There are no known asteroids the size of Texas that have even the slightest chance of hitting Earth. The only known Texas-sized asteroid is Ceres, which has a stable orbit in the asteroid belt and could never hit Earth.
How long ago did the oldest dinosaur die?
my answer is dinosaurs died 65 million years ago when an asteroid crashed into the earth
How long would it take to get to the asteroid belt?
The time it takes to reach the asteroid belt can vary based on the spacecraft's speed and trajectory. For example, NASA's spacecraft Dawn took about four years to reach the asteroid belt from Earth. The distance between Earth and the asteroid belt can range from 2 to 3 astronomical units (AU), with 1 AU being the average distance between Earth and the Sun.
How long does it take to get from the earth to the asteroid belt?
The time it takes to travel from Earth to the asteroid belt depends on the spacecraft's speed and trajectory. Generally, missions to the asteroid belt can take anywhere from about six months to several years. For instance, NASA's Dawn spacecraft took about four years to reach the asteroid belt after its launch in 2007. The specific duration varies based on the mission's design and the position of the planets during the journey.
What is the revolution of the asteroid belt around the sun?
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.
