Learn the jaw-dropping answer to how many planets are in the universe - plus Solar System and galaxy breakdowns.
He found that — given our current understanding of the universe and the laws of physics — there should be 7 times 10 20 planets in the universe. That’s 7 followed by 20 zeroes or 70...
In order from the Sun, they are four terrestrial planets (Mercury, Venus, Earth and Mars); two gas giants (Jupiter and Saturn); and two ice giants (Uranus and Neptune). All terrestrial planets have solid surfaces. Inversely, all giant planets do not have a definite surface, as they are mainly composed of gases and liquids.
With an estimated ~2 trillion galaxies in our observable Universe, we can finally make an accurate estimate of the total number of planets. The enormity of cosmic “chances” for life may ...
The running counter of known exoplanets – as of this writing – stands at 4,108 confirmed worlds. But astronomers are surprisingly good at figuring out what they can’t see.

The eight planets in our Solar System, in order from the Sun, are the four terrestrial planets Mercury, Venus, Earth, and Mars, followed by the two gas giants Jupiter and Saturn, and the ice giants Uranus and Neptune.
The solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. There are five officially recognized dwarf planets in our solar system: Ceres, Pluto, Haumea, Makemake, and Eris.
How many planets are there in the Solar System, and how many planets are there in the whole Universe? It depends who you ask.
