6 FAQs about [Our solar system outer planets contain]
What are the outer planets of the Solar System?
The solar system coalesced from a cloud of gas and dust particles, giving rise to the sun and the inner and outer planets. The inner planets consist of those orbiting inside the asteroid belt–Mercury, Venus, Earth and Mars. The outer, or Jovian, planets existing beyond the asteroid belt consist of Jupiter, Saturn, Uranus and Neptune.
What type of planets are Mercury, Venus, Earth, and Mars?
The first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets. The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young.
How many planets are there in the solar system?
There are five planets from our Sun, with Jupiter being the largest. Jupiter is more than twice as massive as all the other planets combined. NASA’s Planetary Science missions to the outer solar system help help scientists understand more about Earth and the formation and evolution of the solar system.
What are some of the smaller bodies in the Solar System?
Our solar system is made up of a star, eight planets, and thousands of smaller bodies including dwarf planets, moons, asteroids, and comets. The solar system includes the Sun, eight planets, five officially named dwarf planets, and hundreds of moons, and thousands of asteroids and comets.
Are there planets outside our Solar System?
The ongoing search for planets outside our solar system, particularly gas giants similar to the outer planets, offers a tantalizing glimpse into the potential diversity of celestial bodies in the universe.
Which planetary system supports life?
The Solar System is the gravitationally bound system of the Sun and all celestial bodies that orbit it. This includes planets, moons, asteroids, comets, dwarf planets, and countless particles of dust and ice. It is our cosmic neighborhood and the only planetary system known (so far) that supports life.
