List of Solar System objects by size

The following objects have a nominal mean radius of 400 km or greater. It was once expected that any icy body larger than approximately 200 km in radius was likely to be in hydrostatic equilibrium (HE). [7] However, Ceres (r = 470 km) is the smallest body for which detailed measurements are consistent with hydrostatic equilibrium, [8] whereas Iapetus (r = 735 km) is the largest icy body

Solar System

The solar system consists of a central star, the sun, and all of the smaller celestial bodies that continuously travel around it, including our very own Earth. This star grew larger and larger as it collected more and more of the dust and gas that collapsed into it. Further

Stars

Astronomers estimate that the universe could contain up to one septillion stars – that''s a one followed by 24 zeros. Our Milky Way alone contains more than 100 billion, including our most well-studied star, the Sun. Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. []

How Many Stars are in the Solar System?

In our solar system, there is only one star that we know of – the sun! Our solar system is very unique in that is only has one star. Most other solar systems have at least two stars. These are called binary systems. Some solar systems with as many as six stars have been observed Continue reading "How Many Stars are in the Solar System?"

Planetary Systems

Planetary Systems Our solar system consists of the Sun, whose gravity keeps everything from flying apart, eight planets, hundreds of moons, and billions of smaller bodies – from comets and asteroids to meteoroids and tiny bits of ice and rock. Similarly, exoplanetary systems are groups of non-stellar objects circling stars other than the Sun, and []

Astronomy

Astronomy - Solar System, Planets, Stars: The solar system took shape 4.57 billion years ago, when it condensed within a large cloud of gas and dust. Gravitational attraction holds the planets in their elliptical orbits around the Sun. In addition to Earth, five major planets (Mercury, Venus, Mars, Jupiter, and Saturn) have been known from ancient times. Since then

The Sun is the Solar System''s star and by far its most massive component. Its large mass (332,900 Earth masses), which comprises 99.86% of all the mass in the Solar System, produces temperatures and densities in its core high enough to sustain nuclear fusion of hydrogen into helium. This releases an enormous amount of energy, mostly radiated into space as electromagnetic radiation peaking in visible light.
