Strictly speaking 8 planets. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus & Neptune.
The most found around a ExtraSolar star is 5 around the star 55 Cancri A.
The star is a yellow main sequence star of spectral type G8 V, with 0.95 solar masses and a diameter of 1.152 solar diameters.
It is actually in a binary system with 55 Cancri B which is a very small Red dwarf with 0.13 solar masses, 0.3 solar diameters and a separation of 1,000 AU.
The planets are :-
- 55 Cancri Ae - Mass=0.034Mj - Semi Major Axis=0.038AU - Orbital Period=2.81705days - Eccentricity=0.07
- 55 Cancri Ab - 0.824Mj - 0.115AU - 14.65162days - 0.014
- 55 Cancri Ac - 0.169Mj - 0.240AU - 43.93days - 0.086
- 55 Cancri Af - 0.144Mj - 0.781AU - 260days - 0.2
- 55 Cancri Ad - 3.835Mj - 5.77AU - 5218days - 0.025
Just a small note the planets are named according to when they were discovered and follow the internationally recognised format of the star name followed by the lower case b for the 1st found, lower case c for the 2nd and so on.
What else can I help you with?
Where are ExtraSolar planets found?
Extrasolar planets are planets found orbiting stars other then our own.
Is Jupiter the largest planet in space apart from the sun?
No. Jupiter is the largest planet in our solar system (the sun is a star, not a planet), but not the largest in existence. Planets larger than Jupiter have been found orbiting stars other than the sun.
How many planets orbit a star?
The number of planets that orbit a star can vary widely. In our solar system, there are eight planets orbiting the Sun. However, many other stars in the universe have been found to host multiple planets, with some systems containing as many as seven or more. Overall, discoveries from exoplanet research suggest that most stars may have at least one planet orbiting them.
The largest planets of your solar system are found between which 2 planets?
mars and uranus
Is Kepler a planet?
No. Kepler is a telescope created to find planets orbiting other stars. Planets found using it are given designations beginning with Kepler, such as Kepler 440b.
Where are the planets found?
Orbiting stars. We know of eight planets orbiting our Sun, and we know of over 300 planets orbiting other stars.
Where are ExtraSolar planets found?
Extrasolar planets are planets found orbiting stars other then our own.
Is our sun the only star that has planets orbiting around it?
No. Other stars have been found to have planets orbiting them.
Is Jupiter the largest planet out there?
Jupiter is the largest planet in our solar system, but not the largest planet of all. Planets larger than Jupiter have been found orbiting other stars.
Is Jupiter the largest planet in space apart from the sun?
No. Jupiter is the largest planet in our solar system (the sun is a star, not a planet), but not the largest in existence. Planets larger than Jupiter have been found orbiting stars other than the sun.
What is a exoplants?
Exoplanets refers to planets to that have been found orbiting stars other than the sun.

What is the largest planet found next to mars?
jupiter is the bigger planets
Who found the world's largest prime number?
There is no such thing as a largest prime number - there can't be. The largest KNOWN prime number was found by the GIMPS project.
Do other galaxies have planets as well?
Yes, other galaxies also have planets. Just like in our own galaxy, the Milky Way, planets can be found orbiting stars in other galaxies. The study of exoplanets in other galaxies is an active area of research in astronomy.
