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

I don't get the difference. "Tumble end-over-end" is just that - rotate around their axis.
What is a chunk of rock that is found between Mars and Jupiter called?
A chunk of rock found between Mars and Jupiter is called an asteroid. These rocky objects are leftovers from the early formation of the solar system and are primarily located in the asteroid belt between the orbits of Mars and Jupiter.
What was the object that struck the earth over 4 billion years ago?
It is believed that a Mars-sized object, often referred to as Theia, struck Earth over 4 billion years ago, leading to the formation of the Moon. This collision altered Earth's composition and had a significant impact on its early development.
What is larger than a terabyte?
1024 terabytes equals 1 petabyte, 1024 petabytes equals 1 exabyte, 1024 exabytes equals 1 zetabyte, and 1024 zetabytes equals 1 yottabyte. Stay tuned...
What does from the rust belt to the sun belt mean?
"From the Rust Belt to the Sun Belt" refers to the demographic and economic shift in the United States from the industrial regions in the Northeast and Midwest (the Rust Belt) to the warmer, more economically vibrant areas in the South and Southwest (the Sun Belt). This transition began in the late 20th century as manufacturing jobs declined in the Rust Belt due to deindustrialization, while the Sun Belt experienced growth in sectors like technology, agriculture, and tourism. The phrase encapsulates broader trends of migration, economic opportunity, and changing lifestyles as people seek better living conditions and job prospects.
How was asteroid 12088 Macalintal named?
12088 Macalintal is an asteroid named after Filipino Jeric V. Macalintal, a high school student cited for winning the 2002 Intel International Science and Engineering Fair in Louisville, Kentucky with his teammates Richard K.S. Manapat and Allan Estrella
How can humans use the asteroid belt?
you would need too have good doging skills if you where to take a ship
What keeps all planets asteroids and comets in orbit around the sun?
The force of gravity. All those objects have a force acting between them and the Sun. For the less massive objects the force is less, but mass and force are proportional so the force produces an acceleration that depends only on the object's distance from the Sun.
All the objects in orbit would travel in a straight line without a force acting on them, but the pull of the Sun causes them to accelerate or curve continuously towards the Sun. This is a consequence of the law of gravity and the laws of motion, discovered in the late 1600s.
Acceleration is the rate of change of velocity, which includes both speed and direction.
How often do objects big enough to create craters like the Meteor Crater impact Earth?
We can't be certain, but on the order of once in 50,000 years. It depends on where the object strikes; 15,000 years ago, a comet or large meteorite impacted northern Canada, causing an abrupt cooling period known as the Younger Dryas. About 5300 years ago, an object may have crashed into the Indian Ocean, causing tsunami waves that would have swept the shores of eastern Africa, western Australia, most of India, and into Mesopotamia. This possible tsunami may have inspired the similar "world wide flood" legends such as the Gilgamesh epics in Sumeria, some Dreamtime stories from the Australian native cultures, and a guy named Noah.
And then there was the Tunguska, Siberia explosion in 1908....
What is the risk of dying from an asteroid?
The math looks wonky because of the disparity of the numbers. There are usually two or three airplane crashes each year, but only a couple of hundred people are killed in each one.
The odds of an asteroid impact are very low indeed - but if a big one does hit, it could easily kill BILLIONS of people. It could wipe out the human race, or extinguish life on the Earth completely. An asteroid or large meteor or comet or something hit northern Canada about 13,000 years ago and is believed to have caused the "Younger Dryas" mini-ice age and killed most of the humans on North America at the time. The tsunami in Indonesia killed 300,000 people five years ago. If an asteroid were to strike the Indian Ocean, the resulting tsunami could kill a hundred times as many.
So it can't really be the same. However if you are in the place of were the Plane or Asteroid hits the planet then it could be the same.
What is the impact hypothesis?
The giant impact hypothesis states that the moon was formed after a planet called Thei slammed into the Earth right after the Earth came into existence.
Why cant you live on asteroids?
Asteroids have very little gravity, no atmosphere, and no protection from solar radiation. So they cannot support life.
What are some characteristics of asteroids?
The composition of asteroids can vary widely. The defining characteristics of asteroids are that they are at least 10 meter in diameter, and that they orbit the Sun - NOT a planet, in which case they would be called moons.
Why are earth's metals deep underground?
Because Asteroids Hit earth and the minerals go into the ground or get buried deep into the sea . The minerals the grow underwater and deep underground .
What happened to the asteroid that hit Russia?
The object entered the atmosphere at a shallow angle. Its rapid movement heated the air around it to extreme temperatures, which vaporized parts of it, and placed extreme stress on it. The asteroid then disintegrated at an altitude of 20 to 30 miles above the city of Chelyabinsk, generating an enormous fireball and subsequent shockwave. Most of the asteroid was vaporized int he process, but small fragments reach the ground west of Chelyabinsk.
Why is the risk of dying from a asteroid greater than dying from a car wreck?
It is an odd result of the potnetial for a high-impact low-probability event. Once in a very long while Earth is struck by a relatively large asteroid. If such an event were to happen today in a populated area, it could easily result in many millions of deaths.
Fatal car wrecks occur far more frequently than meteorite impacts, but rarely kill more than a few people.
What are examples of superstitious beliefs about comets or asteroid with scientific basis?
There are none. By definition, a supersition does not have a scientific basis.
What was the name of the asteroid that killed the dinosaurs?
The asteroid that thrust the dinosaurs into extinction is known as the "Chicxulub" asteroid (although this is one of the many competing ideas as to how the dinosaurs became extinct).
Answer 2: Listing some speculations as to what happened to them, Princeton scientist G. L. Jepson stated:
"Authors with varying competence have suggested that dinosaurs disappeared because the climate deteriorated . . . or that the diet did. . . . Other writers have put the blame on disease, parasites, . . . changes in the pressure or composition of the atmosphere, poison gases, volcanic dust, excessive oxygen from plants, meteorites, comets, gene pool drainage by little mammalian egg-eaters, . . . cosmic radiation, shift of Earth's rotational poles, floods, continental drift, . . . drainage of swamp and lake environments, sunspots."-The Riddle of the Dinosaur.
It is apparent from such speculation that scientists are not able, with any certainty, to answer the question: What happened to the dinosaurs?
University of Arizona scientist David Jablonski concludes that 'for many plants and animals, extinction was abrupt and somehow special.Mass extinctions are not merely the cumulative effects of gradual dyings. Something unusual happened.' Their arrival was also abrupt. Scientific American observes: "The sudden appearance of both suborders of the pterosaurs without any obvious antecedents is fairly typical of the fossil record." That is also the case with dinosaurs. Their relatively sudden appearance and disappearance contradicts the commonly accepted view of slow evolution
That's a description of meteoroids.
