Their masses are similar to Jupiter but they are very close to the central star therefore very hot.

Why are many of the newly detected extrasolar planets called hot Jupiters?

Many newly detected extrasolar planets are called hot Jupiters because they are large, gaseous planets with characteristics similar to Jupiter, but they orbit very close to their host star. This proximity to their star causes them to have high surface temperatures, hence the term "hot."


What are the names of the planet that are not in your solar system?

Planets that are not in the solar system are called extrasolar planets, or exoplanets.


What are star planets called?

That doesn't make sense. There are stars, and there are planets. If you mean "planets around stars, other than the Sun", those are usually called "extrasolar planets" or "exoplanets".


Are there planets outside your Solar system?

Yes, there are over 200 more planets outside the solar system, these planets are called extrasolar planets. There are also more then 170 solar systems inside of the Milky Way, on average astronomers find around 25 new planets a year.


What are the planets outside of our solar system called?

Planets outside of our solar system are called exoplanets. These are planets that orbit a star other than our Sun. Exoplanets have been discovered through various methods, including transit observations and radial velocity measurements.


Are there new discovered planets?

The current planets being discovered are called "Exoplanets" or "Extrasolar Planets" which means they are planets found outside of our solar system. New ones are constantly being discovered. We are currently getting closer to discovering one within the habitable zone of another star.


What is exo-planets?

"Exoplanets" are planets around stars, outside of our solar system. They are also called "extrasolar planets", "extra" here meaning "outside". It is an imaginary planet created by SM entertainment for their new K POP group EXO. It is said to be the homes of these 12 members


How many planets are in the galaxy way?

We hardly know yet. Planets other than those in our own solar system (called "extrasolar" planets or "exoplanets") have only been discovered in the last ten years or so. About a thousand are known, but astronomers feel there must be many, many more.


Are there planets further than our solar system?

Yes. They are called "exoplanets" and they orbit other stars. They have only been detected recently.


Are there any known planets that have a gravational pull weaker than the dwaf planet Pluto?

I don't think so. No official "planet" in the Solar System has such a weak gravity; most of the so-called "extrasolar" planets (i.e., outside our Solar System) are quite a bit more massive than Earth, since such planets are easier to discover.Other dwarf planets in the Solar System may have a weaker gravity, if you want to count those.


What planet do most known extrasolar planets resemble?

Be cause we can see the big ones more easily, especially those close to their star (because they transit/orbit with a short time interval) most exoplanets are Jupiter like (or larger) and are hot. Hence they are called Hot Jupiters.


What is a planet outside the solar system?

A planet found outside of our solar system is called an "exoplanet" or "extrasolar planet"
