Asteroids

Asteroids, or planetoids, are rocks larger than meteorites but smaller than planets that orbit around the Sun.

When was the last asteroid to hit earth?

User Avatar

Asked by Wiki User

The Earth has undoubtedly been struck by many different asteroids over the past few billion years, though the signs of many have been eroded away by weather and geological changes. Among the more well known places of such collisions are the 110-mile Chicxulub Crater at the end of the Yucatán Peninsula (which ended the dinosaurs), the 4,000-foot wide Meteor Crater in Arizona, and the site of the Tunguska River from the overhead detonation of an asteroid in 1908.

What type of asteroid is Abai?

Asked by Wiki User

There is no specific asteroid named "Abai" that is widely recognized or recorded in scientific literature. It is possible that "Abai" may refer to a fictional asteroid or a lesser-known one that has not been extensively studied or categorized.

Pieces of space debris that are smaller than the smallest asteroid?

User Avatar

Asked by Wiki User

Pieces of space debris that are smaller than the smallest asteroid are commonly referred to as "space junk" or "microdebris." These can include fragments of satellites, rocket parts, or even paint flecks that have broken off from larger objects in space. Despite their small size, they can still pose a threat to spacecraft and satellites due to their high speeds and the potential for collisions.

Are asteroids strange balls of light that appear from no where?

User Avatar

Asked by Wiki User

No, asteroids are not strange balls of light that appear from nowhere. They are rocky, irregularly shaped objects that orbit the Sun, primarily found in the asteroid belt between Mars and Jupiter. Occasionally, when an asteroid enters Earth's atmosphere, it may create a brilliant fireball known as a meteor.

Most asteroids in your solar system travel in a belt between which planets?

User Avatar

Asked by Wiki User

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.

What type of asteroid that would appear darkest and reflect the least light?

User Avatar

Asked by Wiki User

The type of asteroid that would appear darkest and reflect the least light is a carbonaceous or C-type asteroid. These asteroids are rich in carbon compounds and have a low albedo, meaning they reflect only a small percentage of light that hits them. Their dark color is due to their composition and the presence of organic compounds.

What is the main difference between an asteroid an a meteoriod?

User Avatar

Asked by Wiki User

The main difference between an asteroid and a meteoroid is size. Asteroids are larger objects, typically measuring more than 10 meters in diameter, while meteoroids are smaller, ranging from a few meters down to dust-sized particles. Additionally, asteroids are usually found in the asteroid belt between Mars and Jupiter, while meteoroids can be found in various places, including the asteroid belt, as well as comets or other sources.

The orbital period of asteroid 12867 Joëloïc is approximately 3.92 years or 1430 days. It completes one orbit around the sun in this time.

An asteroid can best be described as what?

User Avatar

Asked by Wiki User

An asteroid is a small rocky object that orbits the Sun, typically found in the asteroid belt between Mars and Jupiter. They are remnants from the early formation of the solar system and can vary in size from small boulders to objects several hundred kilometers in diameter.

What kind of damage would a large asteroid do to eartth?

User Avatar

Asked by Wiki User

A large asteroid impact could cause significant damage to Earth. The exact scale of destruction would depend on the size and composition of the asteroid, as well as the location of impact. It could potentially cause massive tsunamis, widespread fires, and release of harmful gases and dust into the atmosphere, leading to global climate change and potential extinction events.

What are killer asteroids?

User Avatar

Asked by Wiki User

Killer asteroids, also known as potentially hazardous asteroids (PHAs), are space rocks that have the potential to collide with the Earth and cause significant damage or even mass extinction. These asteroids are typically larger than 1 kilometer in diameter and follow orbits that bring them close to our planet. However, the term "killer asteroids" is used more in popular culture rather than the scientific community.

Why is it good that most asteroids are in the same plane as the earth?

User Avatar

Asked by Wiki User

The fact that most asteroids are in the same plane as Earth, known as the ecliptic plane, is beneficial for a couple of reasons. First, it makes it easier for astronomers to observe and study these asteroids. Second, it reduces the likelihood of catastrophic asteroid collisions with Earth, as they are confined to this plane rather than randomly scattered throughout space. This alignment allows for more efficient monitoring and tracking of these objects.

When will the next mass extinction occur?

User Avatar

Asked by Wiki User

This is answers.com, not the psychic network.Nobody knows. Various people have predicted various things, but until one of them happens, we won't know for sure.

At one time it was believed that mass extinctions were periodic, and some analyses suggested we were about due for one ... but as more data has come in, it now looks like the periodicity may have been a statistical coincidence, and that smaller extinction events occur all the time. There was a relatively recent one in the oceans about two million years ago, for example (the last really major one was the K-Pg event 66 million years ago, widely thought to have been caused by an asteroid impact).

How to calculate if an asteroid will hit the earth?

User Avatar

Asked by Wiki User

There is essentially no chance of any given asteroid ever hitting the Earth, because those with orbits that made them likely to hit the Earth have already hit the Earth. So it's not something you really need to worry about.

If you're just curious... well, really, you don't want to know that badly. It comes down to solving n-body gravitational equations, and for any reasonably sized n (i.e. larger than, say, 3) there is no known exact solution except in special cases, so you have to use numerical methods and hope the interesting bits don't get lost in rounding errors.

How fast can an asteroid go?

Asteroids orbit the sun at several tens of thousands of miles per hour. The speed varies depending on the orbit.
