Asteroids

Asteroids and comets can bring elements and compounds that are not abundant on Earth, such as precious metals. They also carry water and organic molecules, which may have been essential for the development of life on our planet. However, they can also pose a threat if they collide with Earth, leading to potential devastation.

An asteroid could hit Earth anywhere, but the most likely impact locations are in the ocean due to the vast coverage of water on our planet. Cities along coastlines are also at higher risk. However, the probability of a direct impact on a populated area is very low.

Asteroids are categorized into three basic groups: C-type (carbonaceous), S-type (silicaceous), and M-type (metallic). These groups are based on their composition, with each group having distinct characteristics based on the types of materials they are made of.

Comet Elenin (C/2010 X1) was first discovered on December 10th by Leonid Elenin. I have not yet seen detailed descriptions of its orbit, but early calculations indicate that it will probably be visible to the naked eye in late August or early September 2011.

It's not going to hit the Earth; it MAY come within about 0.4 AU but not much closer.

That is not proven as we do not know the size of the meteor as NASA have not give us the measurements. NASA have also given a warning to all their employees to make sure their families are safe on October the 16th.

Comets are a mix of dust, rock, and ice, while asteroids are primarily made of rock and metal. Comets usually have a tail when they approach the Sun due to the melting of the ice, while asteroids do not have tails.

Phobos is in a synchronos orbit round Mars. This means that (like our moon,) it rorates once for each orbit it makes and it therefore always presents the same face to Mars.

The orbital (and thus rotational) period of Phobos is 7h 39.2min.

yes any asteroid can be seen which is in our solar system can be seen.they are very small so they can not be seen through the naked eye(but an asteroid called vesta which was discovered in 1807 is the only asteroid which can be seen).you will need a telescope to see and to observe asteroids but since space is dark and also since asteroids are small and dark we can see them even better through bigger telescopes,radio telescopes, and orbiting telescopes(Hubble).

The probability of a meteorite the size of a car hitting the Earth is very small. While it is difficult to provide an exact probability due to the unpredictable nature of meteorite impacts, the likelihood of a specific-sized meteorite hitting the Earth is rare. Earth's atmosphere provides some protection by burning up smaller meteoroids before they reach the surface.

The current estimate is that there are over 1,000 known asteroids with a diameter of 0.5 miles or larger that come close to Earth's orbit, but many more smaller ones exist. The actual number may vary as new asteroids are discovered and others go out of range.

The asteroid belt is located between the orbits of Mars and Jupiter in our solar system. It is a region where millions of rocky objects, varying in size from small pebbles to large asteroids, orbit the sun. The largest object in the asteroid belt is Ceres, which is classified as a dwarf planet.

The largest asteroid in our solar system is called Ceres, and it is located in the asteroid belt between Mars and Jupiter. Ceres is classified as a dwarf planet due to its size and is about 590 miles (940 kilometers) in diameter.

Most asteroids exist in the asteroid belt, which is located between the orbits of Mars and Jupiter. This region is characterized by a large concentration of small rocky bodies that orbit the Sun. Some asteroids can also be found in other regions of the solar system.

Yes, comets and asteroids can break up due to various factors such as collisions or gravitational forces, leading to the formation of smaller rocks called meteoroids. These meteoroids can then enter the Earth's atmosphere and if they survive the fiery passage, they are known as meteors or shooting stars.

Asteroids hit the moon because the moon lacks a protective atmosphere like Earth's that can burn up or break apart incoming objects. Over time, the moon's surface has been bombarded by asteroid impacts due to the lack of atmospheric protection.

Planets are generally larger than asteroids. Asteroids are small rocky bodies that orbit the Sun, while planets are larger celestial objects that have cleared their orbit of other debris. Some asteroids can be quite large, but they are still dwarfed by the size of planets.

The terminology of space debris entering the Earth's athmosphere is a question of timing.

Outside the athmosphere, the debris is considered a 'meteoroid.'

Upon entering the athmosphere and while falling to the Earth, the debris is called a 'meteor.'

After striking the Earth, whatever material did not disintegrate is called a 'meteorite.'

So when you see a 'shooting star,' it is not a meteorite. It is technically a 'meteor.' Only after you find it on the ground is it a 'meteorite.'

Yes, it is possible for moons to be asteroids that were captured by a planet's gravity. This scenario typically occurs when a passing asteroid is caught in the gravitational field of a planet and becomes its moon.

Cerus, officially known as 1 Ceres, is the largest object in the asteroid belt between Mars and Jupiter. It has a mass of about 9.4 x 10^20 kg.

Based on Newtonian Laws of Motion, asteroids are still under the original velocity imparted to them when they were made. The only external influences are the gravitational pull of the sun and other celestial objects.

The asteroid belt, is a "collection" of asteroids circling the Sun in between the orbits of Mars and Jupiter. A collection cannot have an atmosphere. A single asteroid does not have enough mass to "hold" on to an atmosphere.

Asteroids and meteors are large rocks that float freely through space. They are rocky objects that orbit the sun and can range in size from a few meters to hundreds of kilometers in diameter. Some asteroids can be found in the asteroid belt between Mars and Jupiter, while others orbit in other regions of the solar system.

An asteroid is a relatively small object in space composed primarily of rock and/or metal. An asteroid belt is a region in space around a star that has a higher then normal concentration of asteroids.
