Most of the moons are large enough to be spherical in shape, but a few have the more potato-like shapes of asteroids. Which of the following statements about the moons of the jovian planets is not true? The shape of liquid objects is a response to the forces acting upon them tempered by the viscosity of the liquid. A chondrite / ˈ k ɒ n d r aɪ t / is a stony (non-metallic) meteorite that has not been modified, by either melting or differentiation of the parent body.

It is the source of short-period comets. why are the earth and other planets spherical while smaller bodies such as most asteroids are not? Its not surprising that Jupiter, so Large, has many L points with 2 low points being stable enough to harbour non-acreted matter (Trojans) over time. An asteroid is a rocky body which lies in the asteroid belt between Mars and Jupiter. This shows that gravity gets stronger for bigger objects, and weaker the farther away they are from each other. Start studying ASTR 150 Quiz 6.

Asteroid orbits can be nearly circular or … 26) With much smaller bodies, such as the 20-kilometer asteroids we have seen in recent spacecraft images, the gravitational pull is too weak to overcome the asteroid's mechanical strength.

In fact the size order is not exact as there are exceptions. M-type asteroids - metallic, most of the remaining asteroids.
From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid. We find that asteroids are fascinating objects, varying in composition and shape. Instead, Pluto, and other large objects would be classified as Dwarf Planets.

A)The presence of large jovian planets B)There are relatively few asteroids near the Earth C)Most asteriods are small in diameter D)Earth's thick atmosphere and oceans E)All of the above actually reduce the chance of a major impact. The Kuiper belt is a disk-shaped region of space beyond the orbit of Neptune that is dynamically stable. The Oort cloud is much farther out than the Kuiper belt. It is the most volcanically active body in our solar system. Only a handful of the largest members possess enough gravity to pull them into spherical shapes. The Earth too has 5 spherical harmonic low points L1…L5, 4 of which are slightly stable. C-type asteroids - high carbon content or 'carbonaceous', 75% of known asteroids; roughly similar composition to the Sun, minus the volatile elements. Less than 100 known asteroids are retrograde. D) If we could put all the asteroids together, … The m 1 and m 2 refer to the masses of the two objects involved in the interaction, G is the universal gravitational constant and r is the separation between the two objects. Why Pluto is no longer a … The largest asteroid Ceres has been reclassified as a dwarf planet. … S-type asteroids - high silicon or 'silicaceous', 17% of known asteroids. Learn vocabulary, terms, and more with flashcards, games, and other study tools. If planets were bigger, the force between them and the sun would be larger and it would alter their orbits. 26)Which of the following does not explain why there is a small chance for a major impact to occur on Earth? It is a spherical region surrounding the Sun out to near 50,000 AU. They can either orbit a planet or travel aimlessly through the solar system. A) Many but not all orbit the Sun in the asteroid belt. Most of the moons are large enough to be spherical in shape, but a few have the more potato-like shapes of asteroids: Which statement about Io is true? It fits with observations of comets in the planetary region of the solar system, but scientists have yet to observe any object in the Oort Cloud itself. Beyond their shape, there are a number of ways to classify asteroids. The asteroid belt like the Trojan locations are just spherical harmonic ‘Low” points in the Solar System. They are typically quite small object.

Almost all asteroids orbit the sun prograde—the same direction as the planets. They are categorized in two categories, stony and iron-nickel, although most asteroids contain both stony and iron-nickel elements. Let's describe them from smallest to largest. Asteroids, which are smaller than comets, are particles of rock and metal that travel through space. Which statement about asteroids is not true?

Nearly all asteroids are irregular in shape and heavily pockmarked by impact craters. The Oort Cloud is a predicted collection of icy objects farther away than everything else in the solar system. Which statement about Io is true?

Most of the moons are small, and small moons generally are not spherical. Most asteroids tend to orbit relatively close to the plane of the eight planets, but a substantial fraction do not. the larger mass of a planet produces enough gravity to pull it into a round shape what are the most common elements composing the Earth B) Some are more like loosely bound piles of rubble than solid chunks of rock. But average all those small-scale effects out and look at the big picture.
C) Most asteroids are not spherical in shape.
