How Are The Planets Grouped?

The planets of the modern solar system are grouped into several different and sometimes overlapping classifications, as illustrated in the following figure: The planets inside the orbit of the earth are called the Inferior Planets, Mercury and Venus.

What Is The Origin Of The Solar System?

The formation of the Solar System is estimated to have begun 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Most of the collapsing mass collected in the Centre, forming the Sun, while the rest flattened into a Protoplanetary disk out of which the planets, moons, asteroids, and other small solar System bodies formed.

What Properties Do The Planets Share?

The outer planets names are Jupiter, Saturn, Uranus, Neptune, and Pluto. The 4 outer planets closest to the sun are all known as the gas giants. They all have a longer year than the inner planets. And they all are colder than the inner planets.

How and When Was The Solar System Formed?

According to the nebular hypothesis our Solar System began around 4.6 billion years ago when part of a molecular cloud of interstellar gas, which was filled with particles of ice, dust, rock, and other particles, collapsed.

What Other Objects Revolve Around The Sun?

The Terran planets of Mercury, Venus, Earth and Mars. The objects in the asteroid belts. The Jovian planets of Jupiter, Saturn, Uranus, Neptune.

Are There More Than 10 Planets?

There are 9 planets in the Solar System, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

How Were The Planets Made?

According to the best model we have, the planets in our solar system formed from gas and dust surrounding the Sun. Every object exerts force on other objects through gravity.

Can We Live on Any other Planet besides Earth?

It is quite hard for humans to live on other planets as there are no suitable conditions for us to live in. Our bodies' are adapted to live on earth under the pressure of the atmosphere and earth's gravity and any change in this can be fatal.

What is a solar system?

the collection of eight planets and their moons in orbit around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.

Why isn't their oxygen in Space?

Oxygen Cant form in an atmosphere because there is no gravity to condense it all into one cloud.
