How Are 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.

What Characteristics Do The Planets Share?

There are different planets in the solar system which are grouped under the inner and outer planets. Inner planets are close to the sun and include Mercury, Earth and Venus among others and are composed of solid metal surface whereas outer planets are far from the sun and include Neptune, Uranus and Jupiter among others and are gaseous in nature with no solid surfaces but liquid cores.

How And When Was The Solar System Formed?

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?

A partial list of objects orbiting our solar sun would include: The Terran Planets of Mercury, Venus, Earth (Terra), and Mars The objects in the asteroid belts The Jovian planets of Jupiter, Saturn, Uranus, Neptune Myriad numbers of planetesimals outside the orbit of Uranus.

What Are The Nine Planets?

  1. Mercury
  2. Venus
  3. Earth
  4. Mars
  5. Jupiter
  6. Saturn
  7. Uranus
  8. Neptune
  9. Pluto

How Were The Planets Made?

Planets form around stars from clouds of gas, cosmic dust, rocks and any other matter in the area over billions of years. The primary force that leads to planet formation is 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 The Solar System?

Every planet in the Solar System has gravity. Jupiter has a LOT more gravity than we do. Mercury doesn't have much gravity compared to us, but it still does. The Moon has gravity, and Mars has gravity.
