You are very stupid.
mercury, venus, earth, mars. so 4.
the Earth is a planet so it can't have more planets!
Earth has no planets of its own. It is one and has one moon.
they are so many km away
nine planets till 2006 until Pluto was broken down so there was only eight planets in the solar system '
WHO GIVES A DUCK. Why do we need to know? Well I do so give an ANSWER
There would be 21 planets because there is 6 planets not counting Pluto since it is a dwarf planet and so 9+12=21 so remember Pluto is a dwarf planet
Nobody knows for sure, but there is so many, that there might be more planets than people on earth!
8 planets and 5 dwarf planets, so 13 in total. There are some additional dwarf planet candidates that have not been officially categorised yet.
Planets need their stars for heat and light, which are essential for supporting life and maintaining stable surface temperatures. Additionally, the gravitational pull of the star helps to keep planets in orbit around it.
Because for years it was thought that there were 9 planets, which included Pluto. But, in recent years it has been discovered that there are other, smaller, dwalf or minor planets which lay beyond the orbit of Pluto. Some of these dwalf planets are as big or even possibly bigger than Pluto. So, a decision had to be reached to either downgrade Pluto to the status of a dwalf or minor planet or include all of these other objects (and nobody knows precisely how many there are) into the main system of planets. If they were all included allthe minor planets into the major system of planets they would all need to be named, so the decision was taken to downgrade Pluto to simplify matters. So now there are only 8 major planets and many more, mostly un-named and undiscovered minor or dwalf planets.
the terrestrial planets are made of iron cores and the gaseous planets are bigger and are made up of many gases that come together so if u could stand on one of these planets u would sink in goo the gaseous planets also have more gravity
