So why do planets get such terrible names? The short answer is that, like most other newly-discovered astronomical objects, their names follow set conventions, laid out by the International Astronomical Union (IAU).
What are the names of the new planets?
Details: The new planets are called K2-293b and K2-294b. The first is about 2.5 times as big around as Earth, the second about 1.7 times. K2-293b orbits a star about 1,300 light years away, K2-294b orbits a star a little over 1,200 light years distant.

What is Super Saturn?
The low-mass companion J1407b has been referred to as a “Saturn on steroids” or “Super Saturn” due to its massive system of circumplanetary rings with a radius of approximately 90 million km (0.6 AU).
What is the biggest exoplanet?
List
| Exoplanet name | Radius ( R J) | Notes |
|---|---|---|
| HR 2562 b | 1.11 | Most massive planet with a mass of 30 M J, although according to most definitions of planet, it may be too massive to be a planet, and may be a brown dwarf instead. |
| Jupiter | 1 69,911 km | Largest planet in the Solar System, by radius and mass. Reported for reference |
How are planet names chosen?
The tradition of naming the planets after Greek and Roman gods and goddesses was carried on for the other planets discovered as well. Mercury was named after the Roman god of travel. Venus was named after the Roman goddess of love and beauty. Mars was the Roman god of War.

The first part of the name is usually the telescope or survey that found it. In this case “HD” stands for the “Henry Draper Catalogue,” a widely-used star catalog. The number 189733 is the order in which the star was catalogued by position (the 189,733rd star added to the catalog).

What is the new discovered planet?

What is a Jovian planet?
Jupiter, Saturn, Uranus and Neptune collectively make up the group known as the jovian planets. The general structures of the jovian planets are opposite those of the terrestrial planets.
How many exoplanets are there 2021?
To date, more than 4,000 exoplanets have been discovered and are considered “confirmed.” However, there are thousands of other “candidate” exoplanet detections that require further observations in order to say for sure whether or not the exoplanet is real.
What is an extrasolar planet?
SUMMARY: An extrasolar planet, or exoplanet, is a planet outside of our solar system that orbits a star other than our Sun.
Why don’t we have official names for extrasolar planets?
Because the International Astronomical Union (IAU) is not giving extrasolar planets “official” names (comparable to the planets of the Solar system), I currently designate names for the fun. I only name planets after mythology, and I only name prototypical or important planets.
What is a planet outside the Solar System called?
Extrasolar planet, also called exoplanet, any planetary body that is outside the solar system and that usually orbits a star other than the Sun. Extrasolar planets were first discovered in 1992. More than 4,000 are known, and about 6,000 await further confirmation. The planetary system of HR 8799. What makes a planet a dwarf planet?
What are some of the eariest names given to planets?
Some astronomers (or amateurs) desided to give some names to some of the most noted planets. The eariest I could remember was the name “Osiris” given to planet HD 209458 b (possibly the first true extrasolar planet name given). The first planet discovered around a Solar star.
