What are the 3 main group classifications of meteorites?

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.

What is Ceres classified as?

It was once considered the fifth planet, then it was changed to asteroid, and is currently (since 2006) considered a dwarf planet (the smallest one yet, only 590 miles, or 950 km, in diameter)

Hope that helped:)

How long would it take to get to the asteroid belt?

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.

The combined mass of all the asteroids in the asteroid belt is?

about 1500 km in diameter-significantly smaller than the Moon

Do asteroids fall to the earth?

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.

Can you live on an asteroids?

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.

How long is a day on Vesta?

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

Length of a day of asteroid belt?

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.

What color are asteroids?

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.

What planet has more than a thousand rings?

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.

Describe a asteroid belt?

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.

How do meteors get knocked out of the asteroid belt?

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.

Most asteroids are about 3 AU from the Sun What is the best estimate of the orbital period of a typical asteroid?

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.

What do asteroids smell like?

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.

How do police officers use science in daily life?

Chromatography is the most used separation-technique in forensic-chemistry and forensic-toxicology. HPLC and thin-layer-chromatography are often used to analyse samples of blood and urine to search for drugs and toxines as well as to search for toxines in case of a murder or an unexplained death. To identify and quantify a unkown toxine chromatography is mostly combined with mass-spectrometry. But in case of searching for heavy-metals methods of atomic-absorption-spectrometry are more often used instead of chromtography.Gas-chromatography in connection with FID and headspace-analysis is a common technique to quantify the amount of alcohol in a blood-sample.

At least the technique to analyse DNA-samples called "Gel-Elektrophoresis" is also a chromatography-technique.

To analyse paints of faked paintings or documents or car paints in case of an accident or crimes, the IR-spectrometry is the more common technique, it would also be possible to analyse these samples by thin-layer-chromatography or other chromatography-techniques, but IR-spectrometry is more reliable.

How did space probe Galileo get pasted the asteroid belt?

The Galileo probe navigated through the asteroid belt by carefully plotting its trajectory to avoid collisions with asteroids. Mission planners used gravitational assists from planets to adjust Galileo's path and minimize the time spent traveling through the asteroid belt. Additionally, the probe's onboard instruments helped detect and avoid any potential hazards during its journey.

What are some superstitious beliefs about comets meteors stars and transet of planets?

There are many superstitions that comets, asteroids, and meteors are signs of the end of the world. If you research history, you can find that a lot of comets coincide with natural disasters. This has been a big reason that some people believe comets are a sign of doomsday. Again, this is a superstition. The Bible identifies apostates with comets and asteroids.

Approximately when did the mass extinction of dinosaurs occur?

The mass extinction of dinosaurs occurred around 66 million years ago during the Cretaceous-Paleogene (K-Pg) boundary.

What is the Size of the asteroid that killed the dinosaurs?

The meteorite that killed the dinosaurs was roughly 10 km (6.2 mi) in diameter.

Between what planets will you find the asteroid belt?

The largest collection of asteroids is found orbiting the Sun between orbits of Mars and Jupiter, This area is sometimes called the "asteroid belt". Think about it this way: the asteroid belt is a big highway in a circle around the Sun. The asteroids are like cars on the highway, except that they are thousands of miles apart on the average. Even so, sometimes the asteroid cars run into one another. When this happens, the asteroids may break up into smaller asteroids. Scientists think that most asteroids are the result of collisions between larger rocky space bodies.

Asteroids can be a few feet to several hundred miles wide. The belt probably contains at least 40,000 asteroids that are more than 0.5 miles across.

If an asteroid is disturbed by the gravitational pull of a planet, or is involved in a collision, it can be thrown out of the belt and go into orbit as a moon. Some of Jupiter's many small moons were likely once asteroids.

Which is more dense an asteroid or a comet?

Out of the three, planets are far larger than asteroids or comets. The technical definition of a planet is a cosmic mass that's large enough to be rounded by its own gravity, but not so large that gravity causes extreme pressures to heat the object and turn it into a nuclear furnace (a sun).

Asteroids and comets, on the other hand, are basically chunks of matter (rock and possibly ice and gases) that remain, compared to planets, irregularly shaped.

Are asteroids luminous?

Asteroids are not luminous like stars. They do not produce their own light but instead reflect light from the Sun. When they are illuminated by sunlight, asteroids can sometimes appear bright in the night sky.

Jupiter nudges the asteroids through the influence of?

its strong gravitational pull, causing them to potentially change their orbits over time. This gravitational influence from Jupiter is known as orbital resonance, where the asteroids' orbits are synchronized with Jupiter's orbital period. Jupiter's presence can also help to protect the inner solar system from potential asteroid impacts by redirecting or absorbing their trajectories.

What asteroid group does eros belong to?

Eros belongs to the Amor asteroid group, which are a class of near-Earth asteroids that have orbits that bring them close to Earth's orbit. Amor asteroids are named after the asteroid 1221 Amor, which was discovered in 1932.

Asteroids have irregular what?

Asteroids have irregular shapes due to their formation process and lack of gravitational forces to pull them into a spherical shape.
