14.3 Formation of the Solar System

Rotation of the Solar Nebula We can use the concept of angular momentum to trace the evolution of the collapsing solar nebula. The angular momentum of an object is proportional to the square of its size (diameter) divided by its period of rotation (D 2 P) (D 2 P).If angular momentum is conserved, then any change in the size of a nebula must be compensated for by a proportional

6 FAQs about [Large objects in the solar system]

What is the largest object in the Solar System?

The Sun is the largest object in our solar system. Its diameter is about 865,000 miles (1.4 million kilometers). Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest bits of debris in orbit around it.

What is the largest object after the Sun and the planets?

With a diameter of about 5262 kilometers it is the largest object after the Sun and the planets. It was discovered by Galileo in 1610 and is named after the Greek mythological character Ganymede, who was a handsome young man abducted by Zeus to become the divine cup of Olympus.

What is the largest planet in the Solar System?

Our solar system's largest planet is an average distance of 484 million miles (778 million kilometers) from the Sun. That's 5.2 AU. Jupiter is the largest of the planets, spanning nearly 1.75 millimeters in diameter on our football field scale. Jupiter's diameter is about equal to the thickness of a U.S quarter in our shrunken solar system.

What are some examples of small objects in the Solar System?

For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and interplanetary dust cloud. (See also Visited/imaged bodies.)

Which objects are not visible at a planetary scale?

Relative masses of the solid bodies of the Solar System. Earth at 48% and Venus at 39% dominate. Bodies less massive than Pluto are not visible at this scale. Relative masses of the rounded moons of the Solar System. Mimas, Enceladus, and Miranda are too small to be visible at this scale. The following objects have a mean radius of at least 400 km.

Which planets have rocky surfaces?

Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets. They are all small with solid, rocky surfaces.
