What is the origin of large craters on earth?
Large craters on Earth are often formed by the impact of meteorites or asteroids. When a large space rock collides with Earth's surface at high velocity, it creates a crater by excavating and displacing the surrounding material. The force of the impact can lead to the formation of a circular depression with distinctive features.
When would Earth experience a meteor shower?
Well at the moment, we don't know. But the reason we don't often see asteroids around earth, is because Jupiter is help us by sucking in most of the asteroids.
How often do 1km or larger asteroids hit earth?
Fortunately not very often - because if one does hit, it would be a major catastrophe.
Can a meteor impact earth?
Yes, it happens quite often.
Asteroids are often called?
minor planet or planetoids
How often does a comet or an asteroids hit earth?
Actual collisions are pretty rare. Most 'space debris' burns up in the atmosphere long before it hits the planet.
Why do people call asteroids meteors and comets space trashor debris?
People often refer to asteroids, meteors, and comets as space trash or debris because they are remnants from the formation of the solar system that are no longer part of a larger celestial body. Asteroids are rocky objects that orbit the sun, meteors are asteroids that enter Earth's atmosphere and burn up, and comets are icy bodies that release gas and dust as they approach the sun. These objects can be considered "trash" in the sense that they are leftover material floating in space.
What are differences of comets meteoroid's asteroids?
Comets : mostly ice & are often in very distant elliptical orbits. Meteoroids and asteroids are usually rocky and/or metallic, asteroids are found in the asteroid belt (between Mars & Jupiter).
Are comets or asteroids more dangerous?
While asteroids and comets have different constitutions - asteroids are mostly metals and rocks while comets consist of water-ice, dust and rock - with comets potentially being potentially less dense, comets travel much faster than asteroids. An asteroid may travel upwards of 40,000 miles per hour, a comet travels over 150,000 miles per hour.
What is an asteroid call that is smaller than a couple meters wide?
Asteroids smaller than a couple of meters wide are often referred to as "meteoroids." These are small rock or metal fragments in space, typically derived from larger asteroids or comets. When they enter Earth's atmosphere and produce a visible streak of light, they are called meteors, and if they survive the journey and land on the Earth's surface, they are known as meteorites.
Do asteroids have gravity, and if so, how does it compare to the gravity on Earth?
Yes, asteroids have gravity, but it is much weaker than the gravity on Earth. This is because asteroids are much smaller and less massive than Earth, so their gravitational pull is significantly lower.
Why might some people call asteroids space trash?
Some people refer to asteroids as "space trash" because they are often seen as leftover debris from the formation of the solar system, primarily composed of rock and metal. Unlike planets, which have cleared their orbits, asteroids share space with other objects and can be perceived as clutter. Additionally, the term "trash" conveys a sense of potential danger, as some asteroids can pose threats to Earth due to their orbits. However, it's worth noting that asteroids also hold valuable resources and scientific insights.
