The dinosaurs died.
scientists don't know if an asteroid killed the dinosaurs it is just a guess the dinosaurs died 65 million years ago
it shaped the moon
They believe the asteroid that killed off the dinosaur was 30 miles in diameter and impacting the earth at more than 250,000 miles per hour.
Extinction of the dinosaurs.
93 million miles
The event that was marked by an asteroid hitting the Earth 65.5 million years ago near modern day Chixulub in the Yucatan Peninsula in Mexico is known as the K-T or Cretaceous-Tertiary Extinction Event.
Most asteroids are in the Asteroid Belt between Mars and Jupiter. But a few do come close to the Earth; these are called Near Earth Asteroids. You can see a list of NEAs, and the dates that they will come closest to the Earth, at www.spaceweather.com. Asteroids and comets have collided with the Earth in the past, and someday one will collide with Earth in the future. Depending on the mass of the asteroid, the damage could be catastrophic. 65 million years ago, scientists now believe that an asteroid or comet hit the Earth, causing the extinction of the dinosaurs and most life on Earth.
i believe that there was only one era that covered the last 542 million years which was the phanerozoic period
they will all be together
The Asteroid belt lies between the orbits of Mars and Jupiter at an average distance between 186 million miles and 300 million miles, (300 million and 600 million kilometers). The distance from the Sun to the Earth is 93 million miles sometimes referred to as an Astronomical Unit, (AU). The Asteroid Belt is between 2.7 and 4.0 au's from the sun along the ecliptic.
The asteroid belt is located between Mars and Jupiter, It's a couple of million miles away.
It is widely believed that that is the event that caused the extinction of the dinosaurs as well as many other lifeforms on Earth.
