What is the source of meteors we see during a meteor shower?
Meteor showers are actually made up of tiny, dust sized pieces of debris from comets, which burn up as they fall through Earth’s atmosphere, creating the fiery trails of light that are what we see when we watch a meteor shower.
Which of the following is a real piece of evidence pointing to recent geological activity on Pluto?
Which of the following is a real piece of evidence pointing to geological activity on Pluto? Surface regions that suggest glacial movement of frozen ices of nitrogen and methane.
Which of the following best describes the primary difference between asteroids and comets?
Which best describes the primary difference between asteroids and comets? Asteroids are rocky and comets are ice-rich. If we could put all the asteroids together, they would make an object about the size of Earth.
Why didn’t a planet form where the asteroid belt is now located?
Why didn’t a planet form where the asteroid belt is now located? – Gravitational tugs from Jupiter prevented material from collecting together to form a planet. Your meteorite is a fragment from the core of a large asteroid that shattered in a collision. Suppose you find a meteorite made almost entirely of metal.
Why do meteor showers repeat?
METEOR SHOWERS. Meteor showers associated with particular comet orbits occur at about the same time each year, because it is at those points in the earth’s orbit that the collisions occur.
What’s the best time to see the meteor shower?
While many showers are most visible after midnight and before dawn, the Geminids may be visible as early as 10 p.m. in some locations, according to the International Meteor Organization, although the best viewing may begin at around 11 and last until 4 a.m.
When you see the bright flash of a meteor what are you actually seeing quizlet?
Terms in this set (17) When you see the bright flash of a meteor, what are you actually seeing? The glow from a pea-sized particle and the surrounding air as the particle burns up in our atmosphere (In other words, you do not see the particle itself, but only the effects it has on the surrounding air as it burns up.)
Why are there no visible impact craters on the surface of Io?
Why are there no impact craters on the surface of Io? Io did have impact craters but they have all been buried in lava flows. What is the most important reason why an icy moon is more likely to be geologically active than a rocky moon of the same size? Ice has a lower melting point than rock.
What would happen to Jupiter if we could somehow double its mass?
What would happen to Jupiter if we could somehow double its mass? Its density would increase but its diameter would barely change.
Which of the following best describes an asteroid?
The Short Answer: Asteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets. Asteroids are small, rocky objects that orbit the sun. Although asteroids orbit the sun like planets, they are much smaller than planets.
What is the similarities between asteroids and comets?
Asteroids and comets have a few things in common. They are both celestial bodies orbiting our Sun, and they both can have unusual orbits, sometimes straying close to Earth or the other planets. They are both “leftovers” — made from materials from the formation of our Solar System 4.5 billion years ago.
What is the difference between asteroid and comet?
The main difference between asteroids and comets is their composition, as in, what they are made of. Asteroids are made up of metals and rocky material, while comets are made up of ice, dust and rocky material. Asteroids formed much closer to the Sun, where it was too warm for ices to remain solid.
Is the asteroid belt a failed planet?
A region between Mars and Jupiter became the asteroid belt. Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn’t quite get started. However, according to NASA, the total mass of the belt is less than the moon, far too small to weigh in as a planet.
Could a planet form in the asteroid belt?
So why doesn’t the asteroid belt condense and form a planet? First of all, there’s not enough total mass in the belt to form a planet. The belt contains only about 4 percent of the Moon’s mass in asteroids — not enough to form a planet -sized body.
Why can’t we see the asteroid belt?
Because asteroids don’t produce any visible light like stars and galaxies, and they are far too small and dark to reflect enough sunlight to be seen with the naked eye like the visible planets. With a telescope you can see many of the larger asteroids of the belt.
