Asteroids

Rock fragments traveling in space are called meteoroids. When a meteoroid enters Earth's atmosphere and burns up, it creates a streak of light known as a meteor or shooting star. If any part of the meteoroid survives and reaches the Earth's surface, it becomes known as a meteorite.

An asteroid impact can have significant effects on Earth, including causing widespread destruction, tsunamis, wildfires, and a "nuclear winter" effect due to dust blocking sunlight. It can also lead to mass extinctions and long-term changes in the climate and ecosystems. Additionally, asteroid impacts can release energy equivalent to large nuclear explosions and create craters of varying sizes.

The asteroid belt is located between the orbits of Mars and Jupiter.

Yes. Ceres is the only dwarf planet located in the asteroid belt.

The asteroid belt lies between the orbits of Mars and Jupiter and is primarily attracted by the gravitational pull of the Sun. The Sun's gravity influences the motion of the asteroids within the belt, keeping them in relatively stable orbits.

Ceres is pretty much the same age as most other objects in the solar system: about 4.6 billion years.

Most of the asteroids within our solar system can be found within the Asteroid Belt. Located between the orbits of Mars and Jupiter, the Asteroid Belt consists of millions of individual asteroids of varying sizes - from a speck of dust to hundreds of kilometers in diameter. The largest object within the belt is a dwarf planet - Ceres - which has a mass of 9.47x1020kg and a diameter of 476.2km.

If you are referring to the Asteroid that hit the Earth 64.8 million years ago, It decimated the existing dinosaurs and killed off many of the existing life forms on our planet.

The likely mechanism by which an asteroid killed the dinosaurs, 65 million years ago, was that the very large impact threw a large amount of dust and particulate matter into the atmosphere, which then blocked out the sunlight long enough to disrupt the existing food chain.

The interaction of earth-orbiting and Sun-orbiting planetesimals (very large chunks of rocks like asteroids) early in the history of the Solar System led to their breakup. The Moon condensed from this debris.

Generally speaking yes. The largest asteroid is probably Ceres with a radius of about 490 kilometers. A "normal" star like our Sun has a radius of around 696 million kilometers. while some stars are 200 times as large as our Sun. However, there are certain stars that are smaller than Ceres. A typical neutron star has a radius of only 12 kilometers, and a small back hole can have a radius of only 30 kilometers.

A micro black hole (hypothetical in existence will only have a radius of about 0.1 mm!!!!

Comets are believed to have two sources. Long-period comets (those which take more than 200 years to complete an orbit around the Sun) originate from the Oort Cloud. Short-period comets (those which take less than 200 years to complete an orbit around the Sun) originate from the Kuiper Belt. Danish astronomer Jan Oort proposed that comets reside in a huge cloud at the outer reaches of the solar system, far beyond the orbit of Pluto. This has come to be known as the Oort Cloud. Statistics imply that it may contain as many as a trillion comets and may account for a significant fraction of the mass of the solar system. However, since the individual comets are so small and so far away, we have no direct evidence about the actual existence of the Oort Cloud. The Kuiper Belt is a disk-shaped region past the orbit of Neptune roughly 30 to 100 AU from the Sun. The Belt contains many icy bodies which can become comets. Occasionally the orbit of a Kuiper Belt object will be disturbed by gravitational interactions with the giant planets in such a way as to cause the object to take up an orbit that crosses into the inner solar system. Although the Oort Cloud is much farther away from the Sun than the Kuiper Belt, it appears that the Oort Cloud objects were formed closer to the Sun than the Kuiper Belt objects. Small objects formed near the giant planets would have been ejected from the solar system by gravitational encounters. Those that didn't escape entirely formed the distant Oort Cloud. Small objects that formed farther out had no such interactions, and remained as the Kuiper Belt objects.

The meteorite-impact hypothesis proposes that the extinction of the dinosaurs was caused by a large asteroid striking the Earth approximately 66 million years ago. This impact led to massive environmental changes, including huge amounts of dust blocking sunlight and causing a "nuclear winter" effect, which disrupted the food chain and ultimately led to the extinction of many species, including the dinosaurs.

Impact causes an asteroid to blow up because when it hits a bigger solid surface like earth the force causes the fire that was burning it, because of our ozone layer, to spread apart and the meteor shatters making it seem like we were hit by a fireball.

The regular day temperature on Vesta is from -202° F to -70° F, but at the equator during Vesta's perihelion (closest distance to the sun) it may rise to -4 ° F and drop to -310° F in the polar regions during aphelion (farthest distance form the sun)

The largest known asteroid, Ceres, is about 583 miles (940 kilometers) in diameter.

The difference between a comet and an asteroid is asteroids are made up of metals and rock materials, while comets are made up of ice, rocks, and dust. Both of them were formed more than 4.5 million years ago.

It's assumed those asteroids that once were comets have had the ice and dust burned off and now have nothing coming off to make a tail.

The asteroid belt is located between the orbits of Mars and Jupiter.

The main Asteroid Belt orbits at around 3 AU (450 million kilometers) from the Sun, between the orbits of Mars and Jupiter.

There is a second belt of asteroids, the Kuiper Belt, orbiting the sun between Neptune and Sedna. Both asteroid belts contain several planets:

-- The main belt contains Ceres (dwarf planet), Vesta, and Pallas.

-- The Kuiper Belt contains three more dwarf planets and several candidates.

Yes. Such an asteroid must have been part of the core of a once larger asteroid.

No. Asteroids are natural; nothing natural is "pure". There are always other materials mixed in to native ore. If scientists discovered an object of a "pure" metal, they would know that it was artificial, that someone had made it.
