How do you use asteroid in a sentence?
Scientists study asteroids to better understand the early solar system.
Is the total mass of all the asteroids smaller that the mass of the earth?
Yes, the total mass of all the asteroids in the asteroid belt between Mars and Jupiter is estimated to be much smaller than the mass of the Earth. The combined mass of all asteroids is only a small fraction of Earth's mass.
Why do asteroids affect the surface of the Earth and the Moon differently?
Asteroids can affect the Earth's surface more due to its thicker atmosphere, which causes asteroids to experience greater resistance and breakup before impact. On the Moon, with no atmosphere to slow down or break up asteroids, impacts are more direct and create craters that can remain preserved for longer periods of time.
How does the moon protect the Earth from asteroids?
Well, isn't that just the most interesting question you've asked today? You see, the moon's gravity helps to deflect some asteroids away from Earth, acting like a sort of silent guardian in the night sky. It's nature's way of reminding us that even in the darkness, there can be something beautiful and protective looking out for us.
What are the depressions in the moon called?
The depressions on the Moon's surface are called craters. They are formed by the impact of meteoroids, asteroids, or comets hitting the Moon's surface.
Why are scientists concerned about near-Earth asteroids?
Asteroids, even very large ones, actually come close to earth regularly and cause no harm and no effect on life on earth. The concern would be a large asteroid crashing into the earth.
How can you stop an asteroid from hitting earth?
Small asteroids can be deflected by explosives (ordinary or nuclear) if they are far enough away. The problem is getting the explosives there. Asteroids travel at orbital speeds of thousands of kilometers an hour, and a large rocket would be required to reach the asteroid and match its speed, so that it could rendezvous and detonate. Hitting an asteroid with a head-on shot would be extremely difficult if not impossible, and could result in a shower of smaller pieces hitting the Earth.
What are the group of asteroids that may occasionally cross earth?
Asteroids that occasionally cross the orbit of Earth are known as Near Earth Asteroids. Asteroids that both cross the orbit of the Earth and are large enough to pose a significant threat in the event of an impact are known as Potentially Hazardous Asteroids.
What are facts about Apollo asteroids?
Apollo asteroids are a group of near-Earth asteroids with orbits that intersect with Earth's orbit. They are named after the first asteroid of this group discovered, 1862 Apollo. Some Apollo asteroids are classified as potentially hazardous asteroids due to their close approach to Earth.
Are asteroids larger then earth?
asteroids vary in size from rock size to earth size and bigger.
What effect did the asteroids have?
masive craters formed and the asteroids shatered thanks for reading this
Which of these hit the earth comets or asteroids?
It is possible for comets and asteroids to hit Earth, but they are extremely rare events.
Is Costa Rica safe from asteroids?
No. Asteroids can hit anywhere on earth.
What are the names of the asteroids that cross Earth's orbit and Jupiter's orbit?
Main Belt asteroids -- a band of asteroids located in the "missing planet" gap between Mars and Jupiter. None of these are economically attractive in a near term program because they are too far from Earth.Amor asteroids -- asteroids whose orbits approach but do not cross Earth orbit, and whose orbits are further from the Sun than Earth's orbit (i.e., "outside-t" Earth orbit). Many have orbits which reside entirely between Earth and Mars. Some of these are economically attractive in the near term.Apollo asteroids -- asteroids whose orbits cross Earth's orbit. Apollo asteroids spend most of their time outside Earth orbit. Many of these are economically attractive in the near term.Aten asteroids -- asteroids whose orbits cross Earth's orbit. Unlike Apollos, Atens spend most of their time inside Earth orbit. A large percentage of known Atens are economically attractive in the near term.
What would be the effect of this particular comet hitting earth?
If a comet hits the ground than the gravity will be greater or lesser?
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.
Which layer protects earth from asteroids?
The Earth's atmosphere is the layer that helps protect the planet from asteroids. When asteroids enter the Earth's atmosphere, friction causes them to heat up and break apart, reducing the impact of the asteroid on the Earth's surface.
