The Big Questions
An exoplanet is a planet outside our solar system, usually orbiting another star. They are also sometimes called "extrasolar planets," "extra-" implying that they are outside of our solar system. detailed answer Is there life on other planets?

The nearest potentially habitable planet to Earth – Exoplanet
UNSW Australia astronomers have discovered the closest potentially habitable planet found outside our solar system so far, orbiting a star just 14 light-years away. The planet, more than four times the mass of the Earth, is one of three that the team detected around a red dwarf star called Wolf 1061.

Naming of exoplanets
The search for planets beyond the Solar System reaches back to the middle of the 20th century, but the first extrasolar planet (exoplanet for short) around a Sun-like star was only discovered in 1995 (Mayor & Queloz 1995), a breakthrough that was awarded the 2019 Nobel Prize in Physics. As such, exoplanet research is a rather young field in

The giant planets Jupiter and Saturn lead our solar system''s moon counts. In some ways, the swarms of moons around these worlds resemble mini versions of our solar system. Pluto, smaller than our own moon, has five moons in its orbit, including the Charon, a moon so large it makes Pluto wobble. Even tiny asteroids can have moons.

Background Information | What is Exoplanet Watch? – Exoplanet
We call the planets outside of our solar system extrasolar planets, or exoplanets. In the mid-1990''s, scientists started finding ways to detect exoplanets orbiting distant stars. Since then, over 5,000 exoplanets have been discovered, and the list of exoplanet discoveries grows longer all the time.
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
The Complete List of New Planet Names (Exoplanets)
Today more than 5,000 planets have been discovered outside the Solar system. To keep things short, we call them exoplanets (exo = outside). Below you will find a list of every exoplanet with a name, but as you will notice, it is much shorter than the number mentioned above. So let''s clear that up first. How do new planets get their names?
6 FAQs about [Names of planets outside of our solar system]
Do all stars have exoplanets?
Most stars in our galaxy have at least one exoplanet, and many are unlike any of the worlds in the Solar System. Some exoplanets could be habitable and are prime targets in the search for life beyond Earth. What are exoplanets? An exoplanet, short for “extrasolar planet,” is any planet that isn’t in the Solar System.
Do All Stars and exoplanets have names?
All stars and exoplanets have designations, but very few have proper names. The first part of an exoplanet name is usually the telescope or survey that discovered it. The number is the order in which the star was cataloged by position. The lowercase letter stands for the planet, in the order in which the planet was found.
How many exoplanets are in the Solar System?
There are 7,026 known exoplanets, or planets outside the Solar System that orbit a star, as of July 24, 2024; only a small fraction of these are located in the vicinity of the Solar System. [ 3 ]
How do you identify an extrasolar planet?
Exoplanets or “extrasolar planets” are planets found outside our solar system. They are designated by affixing a lowercase letter, starting from “b” towards “z” depending on order of discovery, to their parent star’s Flamsteed designation or catalogue numbers.
Which star has the closest exoplanet?
The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away. The first confirmed exoplanet discovered in the Proxima Centauri system was Proxima Centauri b, in 2016. HD 219134 (21.6 ly) has six exoplanets, the highest number discovered for any star within this range.
Why is a planet called an exoplanet?
The word "exoplanet" derives from the term "extrasolar planet," which hints at its existence beyond the influence of our star. Prior to the 1990s, humanity had never observed a planet beyond the solar system and thus could not confirm such worlds existed.
