Asteroids

503

i am not %100 sure but some think in the begining there we only 3 sons and then the big bang......ect.......then the three sons were smashed into milions of bits so small you could not see them but there were only 3 to make orions belt

but the real reson is that's how God created it

when i wrote sons i ment suns

Only a few have been observed. There are several relatively small Kuiper Belt objects that have tiny moons. Two NEOs (Near Earth Objects) each have two confirmed satellites: 1994-CC and 2001-SN263.

1994-CC (700 m in diameter) is actually smaller than the "moons" of the other NEO and its own satellites are only a few meters in diameter.

There are also asteroid groups that revolve around common centers of gravity for various lengths of time. But asteroids that orbit each other are more properly described as "double asteroids" rather than an asteroid and moon. The term "moon" refers typically to bodies orbiting major planets.

Ceres is smaller than any planet; even smaller than Pluto.

Even if we assume that the central mass is our sun, the question is still insufficient for an answer as just giving the semi-major axis isn't enough. We need to know the minor axis as well to calculate the eccentricity.

Jupiter :P

Like most other asteroids that do so, it would burn up and simply fall to the ground as fine dust particles. If it were to 'skim' the surface of the atmosphere, it would be pulled slightly towards Earth; at the right speed and height, this would cause it to begin orbiting. Otherwise it is likely to either have its travel affected, and pass through on a path bent from its original one before continuing on, or slow down so much that it began falling directly to Earth (in which case it would either burn up or land and make a small crater or splash). If the asteroid were big enough, even by passing close enough to Earth, it can have an effect on the tides on the surface nearest it; it may also begin orbiting, although this has an extremely low probability.

Ceres is part of the asteroid belt.

No. There is no comet or asteroid or meteor going to hit the Earth. Most of it is superstition.

Both meteoroid's and comets are made out of rock and burn up when getting into earths atmosphere.

Asteroids formed from left over materials from when our solar system formed that never formed into a planet.

An asteroid is space debris made up of rock and metal and can range drastically in size. When an asteroid makes a collision course for Earth, it is called a meteor. A meteor that manages to hit the Earth is called a meteorite.

In a massive galactic collision, the stars much further apart than the water droplets in a rain cloud; the odds that any two stars would collide would be astronomical. However, the number of stars IS "astronomical", in the trillions for a big galaxy like the Milky Way and Andromeda, which WILL collide in about 4 billion years. So it's very possible that at least two such stars will collide, with catastrophic results; in all likelihood, the two stars would start to merge and promptly go nova, destroying them.

But as a general rule, stars don't collide.

Even though the planet Earth is very large in comparison to the people who live on it, it is very small in comparison to outer space. It is effectively a small target for comets to hit. And even though the gravitational attraction of the Earth does tend to pull objects such as comets toward it, in most cases the comet (or other object) will still miss, and will then fly past the Earth.

The latest thinking on this subject is as follows: Not all small and sundry asteroids can be stopped from hitting the earth. Those asteroids whose paths and trajectory are fairly known along with their periodicity can be nudged from a collision course to earth by sending a rocket or spacecraft. The proximity of the rocket or spacecraft itself is expected to change the trajectory of the asteroid (in a controlled and calculated manner.) In years to come, science may come up with other additions to this basic concept to successfully deviate the asteroid from its collision course to the earth.

Asteroids are rocky objects that orbit the Sun and are commonly found in the asteroid belt between Mars and Jupiter. Occasionally, asteroids can come close to Earth as they travel through our solar system. If an asteroid were to impact Earth, it could have devastating effects depending on its size and composition. Scientists actively track and monitor asteroids to predict any potential impacts and develop strategies to mitigate any potential threats.

There is no "impact asteroid". An asteroid impact however is when an asteroid hits a planet or moon.

i believe in superstition because it helps us to be learn more but i think with scientific basis......

The Torino Scale measures the potential threat posed by near-Earth objects (NEOs) such as asteroids and comets. It categorizes the impact hazard based on the predicted impact probability and the kinetic energy of the object. This scale helps to communicate the level of danger associated with an incoming NEO.

They don't think so, but it will be very close in 2029. There is more concern about the next time it comes by, but that's really not that far off, it will be in 2036.

_____________________________________________

When Apophis comes close to Earth (and it will be VERY close on an astronomical scale - below the altitude of geosynchronous satellites!) on Friday, April 13, 2029, it WILL MISS. However, we cannot accurately predict PRECISELY how close it will come, and how the orbit of Apophis will be altered by the Earth's gravity.

And when Apophis returns to near-Earth space, on Friday, April 13, 3036, there is a very small chance that it will strike the Earth. However, during the close pass in 2029, we will plant telemetry sensors and radar reflectors which will enable us to track it with perfect accuracy. And if we're smart - and nobody ever accused NASA of being smart! - we will also plant two very large nuclear weapons on Apophis.

Then, several months later, when we've had time to calculate its orbit to see exactly where it will be in 2036, we can determine whether one or both of the weapons should be detonated to nudge Apophis into a safer orbit. And if it turns out that Apophis is not going to hit the Earth in 2036, then we can ignore them and watch the pretty asteroid scoot by. And in 2050 or so, we ought to be able to capture the asteroid and move it into a parking orbit, perhaps in the L4 or L5 points on the Moon's orbit.

Just think; if this all works out, your grandchildren may live in the Apophis Station!
