The International Astronomical Union (IAU) recognises eight planets in our solar system (from closest to sun to furthest);
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
A further five dwarf planets are recognised by the IAU;
Ceres (in the asteroid belt between Mars and Jupiter), Pluto, Haumea, Makemake and Eris.
Several further dwarf planet candidates have been discovered beyond Pluto's orbit, but are yet to be formally classified by the IAU. These include; Orcus, Ixion, Varuna, Quaoar and Sendna among others.
There are also other planets being discovered around other stars, other solar systems - these are known as exo-planets.

Why aren't all the planets stuck together?
As they need space to carry out photosynthesis.
How many planets actually fit in the sun?
All the planets in the solar system would fit in the sun with lots of space left over.
What can be used to explore all of the planets?
Space telescopes w/ cameras
What are all the planets that have planets?
A planet can not have planets.it probably can have planets say somehow 2 planets crashed together then exploded and little pieces come from the planet
What are the effects of planets and stars floating ramdomly in space?
How do you mean float randomly in space? As space is shaped, due to the planets withing them (gravity), all things that want to travel in a straight line will automatically now follow a curved line, even light, and thus it's not random at all but rather that it's following a path already laid out for it, depending on where it is, how many planets are around it and at what speed it's traveling.
Why aren't all the planets stuck together?
As they need space to carry out photosynthesis.
If you add the diameters of all the planets in space together what does it equal?
Nothing - no really nothing at all.
How are all of the planets in the solar system held?
My teacher Mrs. Black said before that it was gravity that holds the planets together in space.
Why do planets have to be in space?
If they aren't in space, then where else can they be?
What do the planets have to do with astronomy?
Astronomy is all about the things in outer space and planets are in outer space.
What is a lie about how planets are formed?
Here is one lie about how planets are formed: One day Zeus took a big doodoo. All his doodoo was floating in space and they clumped together to form the planets.
What is up in space?
Planets,rockets,meteors,comets,and galexies. Many more things are in space I just can't answer them all.
How many planets actually fit in the sun?
All the planets in the solar system would fit in the sun with lots of space left over.
What would happen to the planets if you took away the sun's gravity?
the planets would not receive heat from the sun and all life on earth would cease to exist. also the planets would not rotate or be held in place. the sun is what holds the planets together in orbit.
What planets are in space?
If you are talking about how many planets are in our solar system, the official count of them are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Pluto has been offcially named as a dwarf planet. If you are talking about how many planets are in ALL of space, there are trilllions, more than you can imagine.
Why Is The Space Big?
Because it has all the planets to hold
What are all the all gasy planets?
gassy planets are made of gas that is stuck together by gravity. Also the answer is in the question.
