What are tiny planets that orbit between Mars and Jupiter called?
Tiny planets that orbit between Mars and Jupiter are called asteroids.
When is the next asteroid due to hit?
There are currently no known asteroids on a collision course with Earth. Astronomers around the world continuously monitor the skies for any potential threats, but at this time, there are no imminent impacts predicted.
Meteorites and meteoric dust are usually magnetic because meteors contain what?
The most common magnetic element found in meteorites is iron. Another common element in meteorites is nickelwhich is also magnetic. Some meteorites also contain Cobaltwhich again is also magnetic.
The most common meteorites are H-Group Chonderites which make up about 31% of all meteorites ever found. They also contain the most metal at 15 - 20%.
Of this metal normally about 70% is Iron with about 29% nickel and trace amounts of cobalt along with other non magnetic metals including gold, platinum and silver.
A band of asteroids, also known as an asteroid belt, is a region in space between Mars and Jupiter where a large concentration of asteroids are found. These asteroids vary in size, shape, and composition, and are thought to be remnants from the early solar system. The most well-known asteroid belt is the Main Asteroid Belt, located between the orbits of Mars and Jupiter.
How are asteriods and comets alike?
Asteroids and comets are both celestial bodies that orbit the Sun. They are remnants from the formation of the solar system and are composed of rock, metals, and other materials. However, comets are distinguished by their icy composition and tail of gas and dust when they approach the Sun.
Are meteoroids larger than asteroids?
No, meteoroids are smaller than asteroids. Meteoroids are small rocks or particles in space, ranging in size from dust grains to boulder-sized objects. Asteroids are larger rocky bodies in space that can range in size from a few meters to hundreds of kilometers in diameter.
Has the earth ever been hit with a asteroid and where?
Eventually, sure. But no time soon that we know of. Also, an asteroid need not be a planet-killer, though it will surely make a mighty meteor and a big hole (or splash). Lesser meteroids (mostly comet sheddings; not big enough to own the title of "asteroid") hit the Earth all the time. Many think that the geological record shows that we get a major bombardment about every 26 million years. If so, rest easy, because the last one was 13 million years ago, so we're not due for quite a while.
What is the biggest known asteroid between Mars and Jupiter?
The largest known asteroid between Mars and Jupiter is Ceres. Ceres is considered a dwarf planet and makes up about one-third of the total mass of the asteroid belt.
Approximately how many million kilometers from the sun are most asteroids located?
between 227.9 and 778.3 million kilometers
Where is the asteroid belt located in the atmosphere?
The main Asteroid Belt in the solar system is located between the orbits of Mars and Jupiter. It contains many millions of rocky objects and dust particles, and the dwarf planet Ceres (formerly considered simply the largest of the asteroids).
However, there are other asteroids that orbit outside the main belt; some of them come in as close as Venus, and out as far as Neptune. Beyond Neptune, the Kuiper Belt contains many more icy objects, including three dwarf planets.
What planets are between the asteroid belt and the sun?
The planets between the asteroid belt and the Sun are Mercury, Venus, Earth, and Mars. These four inner planets are also known as the terrestrial planets because they are primarily composed of rock and metal.
The end of the "Mesozoic Era" coincides with the abupt disappearance of almost all large animal life on the Earth, about 65 million years ago. Luis Alvarez determined that a number of interesting factors including a layer of "shocked quartz" and iridium dust that occurred at about the same time, and this led to his hypothesis that a large object had impacted the Earth causing the extinction.
How many seasons were they before the earth got hit by a metorite?
There were no seasons, because no part of the earth was tilted away from it or tilted tword it.
How do space stations avoid being hit by asteroids?
The space station is really never at risk from Asteroids. An asteroid is like a small planet in size, so if by small chance one ever came close to Earth, we would probably all be doomed.
However there is all kinds of space debris that the space station must be protected from. The most common threat is from micro meteorites. These are small particles of space rock that are usually only a few grams in size. It is impossible to avoid them, so spacecraft are designed to survive impacts. There are larger, more dangerous types of debris too, such as broken satellites, lost equipment, or even rocket boosters. The U.S. Strategic Command keeps a catalogue of over 19,000 pieces of space debris 10 cm in diameter and larger. If the space station ever gets too close, it will fire rocket engines to avoid the debris.
What is larger the asteroid or kuiper belt?
The Kuiper Belt is larger than a single asteroid. The Kuiper Belt is a vast region beyond Neptune filled with icy bodies and dwarf planets, while an asteroid is a much smaller rocky and metallic object typically found in the inner solar system.
What is so special about Trojan asteroids?
They orbit the Sun in the same path as Jupiter, and 60° ahead of or behind it.
Yes. The Trojan asteroids orbit along the orbital path of Jupiter at points 60o ahead of and behind it. These regions are two of the "Lagrange points," named after the mathematician who discovered that such orbits could be stable
What is the difference between A belt and B V belts?
"B" series v-belts are wider and transmit more horsepower than "A" series belts. V-belt sheaves for A and B series belts often will accept both A or B series belts. These sheaves will usually have pitch diameters stamped on them for both A and B. You will notice the diameter for the "A" belt will be a little smaller pitch diameter because the "A" belt will ride "down" in the groove farther than the "B" belt. You should be able to "google" on something like "gates v-belts" to see examples.

What is the similarities between a planet or an asteroid?
Ceres has a diameter of 950 km. and a mass of -.95. the closest measurement of the dwarf planets that is closest to Ceres is Pluto. Pluto has a diameter of 2,340 km. and a mass of 13.05. The surface temperature on Ceres is 167 degrees, and Ceres has no atmosphere. Ceres goes in the water frost categorie of planets.
Compare and contrast asteroids and comets?
Both asteroids and comets are celestial bodies in space, but they differ in composition and appearance. Asteroids are mainly made of metal and rock, and are found mostly in the asteroid belt between Mars and Jupiter. Comets, on the other hand, are made of ice, dust, and rock, and come from the outer regions of the solar system. Comets also have a tail that forms when they get close to the Sun, while asteroids do not.
Where do asteroids that fall to the earth come from?
small pieces of debris that are from other comets, asteroid's, etc colliding together
Meteoroids are formed by; Scientists look at what they know--the form and composition of meteorites as the see it in the laboratory and the form and composition of the universe as they see it through their telescopes. They then make a guess--pose a hypothesis--as to how meteorites formed. They test the hypothesis by trying to prove it false. Following are the current theories of how meteorites formed:
Why is it so important for us to know how the dinosaurs became extinct?
It is essential we try to understand how the dinosaurs died out. It is not just for scientific endeavour.
At the end of the cretaceous life on the planet was already in decline. Dinosaurs and other animals were already becoming extinct even before the K-T impact event. It is likely that the impact in the Yucatan was only the final nail in the coffin of an already dieing world.
Unfortunately the extinction rate now mostly because of human activity is far higher than at the end of the cretaceous (some estimates say that the extinction rate now is faster than at any other time in history). If an impact occurred now we need to know as much as we can so perhaps we can survive.
It is unlikely that a 10km or larger asteroid impact would directly affect the International Space Station orbit, as the ISS is located in low Earth orbit, much closer to the Earth's surface than the impact site of such an asteroid. However, the impact could have secondary effects on Earth's atmosphere and environment that may indirectly impact the ISS.
a 50 m colision happens all the time, the last one was in siberia in the early 1920s
in terms of earth scale the impact would be none
but if hits a populate area could be like a nuclear bomb like hiroshima or nagasaki in a smaller scale
