Question: What is the largest known asteroid in our solar system quizlet?

The largest known asteroid is Ceres, which is almost 500 miles in diameter. Some asteroids that come very close to the Earth are called “Earth-grazers”.

Is the largest known asteroid in the solar system?

Asteroids might look dry and barren, but the Solar System’s biggest asteroid — Ceres — is chock full of water, NASA’s Dawn spacecraft has found.

What is the size of the largest asteroid quizlet?

The largest asteroid (Ceres) is 1000 km in diameter. Their total mass would not be significant and added together they would make an object under 2000 km (just over half the moon’s diameter.) They are made of mostly metal and rock as they condensed within the frost line.

What do asteroids and comets have in common quizlet?

What are the 3 largest asteroids in our solar system?

Ceres, Pallas, and Vesta are the three largest asteroids. Even though they are much smaller than the planets (Ceres, the largest asteroid, has only 1% the mass of the Moon), they are still capable of causing changes in the orbits of Mars and the Earth.

What is the largest asteroid near Earth?

The largest known Near-Earth asteroid is 1036 Ganymed with a diameter of nearly 41 kilometers (25.5 miles). Scientists are working to identify Near-Earth asteroids with diameters of 1 kilometer (0.6 mile) or more that may pose a danger of colliding with the Earth.

Where are most of the known asteroids found quizlet?

(Most asteroids are found in the asteroid belt between Mars and Jupiter. Comets are concentrated in two regions: the Kuiper belt just beyond the orbit of Neptune and the much more distant and roughly spherical region known as the Oort cloud.)

What is the size of the largest asteroid?

The largest asteroid is Ceres. Ceres is 1859 miles around the whole asteroid and has a diameter of 588 miles. It is also the only Dwarf Planet without a moon.

What are Trojan asteroids quizlet?

Trojan asteroids or just Trojans, are a large group of asteroids that share the orbit of the planet Jupiter around the Sun. … They have sizes less than 10 km (1866 Sisyphus is the largest discovered so far) and form the majority of the population of Earth-crossing and Potentially Hazardous asteroids.

What do most asteroids and comets have in common?

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.

Why won’t Pluto collide with Neptune quizlet?

Why won’t Pluto collide with Neptune? Pluto orbits the Sun exactly 2 times for every 3 Neptune orbits, which ensures they never come close together. Pluto’s orbit never comes anywhere close to Neptune’s orbit. Actually, a collision of the two is inevitable within the next billion years.
