Asteroids

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.

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.

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.

There are 3 main classifications of meteorites; Stony-iron meteorites, Iron meteorites and Stony meteorites. Stony-iron meteorites are mainly composed of meteoric iron which can be also found in Iron meteorites, Iron meteorites commonly contains iron nickel alloy and the Stony meteorites are the meteorites consists of silicate.

The time it takes to reach the asteroid belt can vary based on the spacecraft's speed and trajectory. For example, NASA's spacecraft Dawn took about four years to reach the asteroid belt from Earth. The distance between Earth and the asteroid belt can range from 2 to 3 astronomical units (AU), with 1 AU being the average distance between Earth and the Sun.

about 1500 km in diameter-significantly smaller than the Moon

Yes, asteroids fall to earth all the time, but most of them don't make it through the atmosphere because it perishes and burns up before it can even hit earth, but nothing to worry about because most of the asteroids that hit earth are relatively small. Hope this helps.

Living on an asteroid would be extremely challenging due to lack of atmosphere, gravity, and resources like water and oxygen. The conditions would be harsh and inhospitable for humans. Additionally, the low gravity could have negative effects on the human body over long periods of time.

A day on Vesta, which is a large asteroid located in the asteroid belt between Mars and Jupiter, lasts about 5.34 hours.

A day is what you experience on a planet that is spinning. Each time the asteroid turns so you face the sun - that's another day. So it depends on if the asteroid you are focusing on is spinning, and how fast.

Asteroids can vary in color depending on their composition. Some can appear grey or brown due to their mineral content, while others may have a reddish hue caused by the presence of materials like iron oxides.

Saturn is the planet with more than a thousand rings. While not all are easily visible, Saturn's ring system is made up of thousands of individual rings, varying in size and brightness, giving the planet its iconic appearance.

The asteroid belt is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt region is also termed the main belt to distinguish it from other concentrations of minor planets within the Solar System, such as the Kuiper belt and scattered disc.

Meteors are rocks that enter Earth's atmosphere and burn up. They can originate from the asteroid belt through collisions, where the impact can knock them out of the asteroid belt's orbit and send them hurtling towards Earth. These celestial bodies become meteors once they enter Earth's atmosphere and create a bright streak of light as they burn up due to friction.

5.2 Earth years
Explanation: Kepler's third law, shown below, relates a planet's orbital period to its orbital radius. T is the planet's orbital period and r is its orbital radius. k is a constant that depends upon the mass of the star at the center of the solar system.so

T2 = kr3

When AU are used in our solar system, k is 1. To solve, cube the orbital radius, so 33 is 27. Then take the square root of the result. The square root of 27 is close to 5.2, so the period of a typical asteroid is close to 5.2 Earth years.

Asteroids do not have an atmosphere, so they do not have a distinct smell. The composition of asteroids varies, but they are typically made up of minerals and metals. If an asteroid were to come into contact with Earth, it would likely smell like the materials it is composed of.
