Exoplanet

An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not then recognized as such. The minimum mass/size required for an extrasolar object to be considered a planet should be the same as that used in our Solar System. Alternatives There is at least

Solar System Facts

Our solar system includes the Sun, eight planets, five dwarf planets, and hundreds of moons, asteroids, and comets. but its existence is predicted based on mathematical models and observations of comets that likely originate there.

The weird space that lies outside our Solar System

The region outside our Solar System is thick with a steady rain of these high-speed subatomic particles, which would be powerful enough to cause deadly radiation poisoning on a less sheltered planet.

List of potentially habitable exoplanets

This is a list of exoplanets within the circumstellar habitable zone that are either under 10 Earth masses or smaller than 2.5 Earth radii, and thus have a chance of being rocky. [3] [1] Note that inclusion on this list does not guarantee habitability, and in particular the larger planets are more unlikely to have a rocky composition. [4]Earth is included for both comparison and reference

ESA

Since 1995, when Michel Mayor and Didier Queloz of the Observatoire de Geneve, discovered the first planet orbiting another star like the Sun, over two hundred more extrasolar planets have been found in more than 170 solar systems outside our own.

Cosmic Milestone: NASA Confirms 5,000 Exoplanets

Finding just three planets around this spinning star essentially opened the floodgates, said Alexander Wolszczan, the lead author on the paper that, 30 years ago, unveiled the first planets to be confirmed outside our solar system. "If you can find planets around a neutron star, planets have to be basically everywhere," Wolszczan said.

Background Information | What is Exoplanet Watch? – Exoplanet

The Sun is the only star in our solar system. When we look up at the night sky, we can see countless stars. There are billions of stars in our Milky Way Galaxy, but we can only see a few of them. There are billions of galaxies in the universe. We call the planets outside of our solar system extrasolar planets, or exoplanets. In the mid-1990

Life in the Universe: What are the Odds?

In our solar system, Earth sits comfortably inside the Sun''s habitable zone. Broiling planet Venus is within the inner edge, while refrigerated Mars is near the outer boundary.
