What Are Extrasolar Planets Called? Here’s the explanation, including the amount

KONTAN.CO.ID – Jakarta. What is are called the Outer Solar Planets? Here’s the explanation, complete with the confirmed amount. Extrasolar Planets, also known as exoplanets, are the names for planets outside the Solar System.

Talking about the universe, there is so much that we may not know yet. Moreover, things that are in outer space, maybe there are still many things that some people don’t know.

In general knowledge, we know the planets, moon, sun, and everything that is neatly arranged in a system that we know as the Solar System.

The Solar System consists of several celestial bodies that have their respective orbits. Like planets, moons, or even millions of other celestial bodies such as meteors, asteroids, and comets.

We know several planets in the Solar System, such as: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and also Neptune.

However, there are still many other planets outside the Solar System that we may not know about. The planets that are outside the Solar System are called the Outer Solar Planets or exoplanets.

Definition of Extrasolar Planets

In simple terms, Extrasolar Planets or exoplanets are planets outside the Solar System. Until now there are thousands of planets that are outside the solar system.

It is known that as of September 1, 2021, there are 4,834 confirmed planets in 3,572 planetary systems, 795 of which have more than one planet.

To find out how many extrasolar planets or exoplanets are, most of them are detected through the radial velocity direct observation method (radial velocity) and other methods other than sensing.

Interestingly, most of the extrasolar planets found are giants like Jupiter. This is due to the limitations of the technology used, so that small extrasolar planets may be difficult to detect.

Here are some important findings related to extrasolar planets or exoplanets:

  • 47 Ursae Majoris b (1996), like the early planet Jupiter.
  • Upsilon Andromeda (1996), The first multi-planet system discovered around a main-sequence star containing three planets that are all Jupiter-like.
  • Gliese 876 b and Gliese 876 c (2000), two planets found orbiting a red dwarf star (Gliese 876(.
  • 55 Cancri (1996), The famous multi-planet system was first discovered in 1996. Contains 5 planets (b, c, d, e, f).
  • HD 10180 (2010), The famous multi-planet system discovered in August 2010. Contains 7 planets (unconfirmed b, c, d, e, f, g, and h)
  • Kepler-1625b, the first exoplanet or exoplanet discovered, has a natural satellite orbiting it.

Thus the understanding of the Outer Solar Planets or exoplanets until the number has been confirmed. Hopefully this information about extrasolar planets can add to your insight regarding things that are in outer space.
