What are the planets without satellites?
Mercury and Venus are the only planets in the solar system which do not have any satellites.
Why do the outer planets have more satellites?
For a short answer: The giant planets have more moons than the terrestrial planets because of their great masses which result in stronger gravitational fields. And giant planets also occupy greater space and hold larger volumes of mass in their surrounding atmospheres.
Do all planets have a satellite?
Most planets in our solar system have natural satellites, which we also call moons. For the inner planets: Mercury and Venus each have no moons. Earth has one relatively large moon, while Mars has two asteroid-sized small moons called Phobos and Deimos.
Why do planets have satellites?
Any dust and ice not incorporated into the planet itself would have coalesced into the regular moons we see today around the giant planets. Because the giant planets gravitationally dominate a very large area, they also can efficiently capture passing objects as moons, which we call irregular satellites.

Which planet has more satellites?
Saturn has overtaken Jupiter as the planet with the most moons, according to US researchers. A team discovered a haul of 20 new moons orbiting the ringed planet, bringing its total to 82; Jupiter, by contrast, has 79 natural satellites. The moons were discovered using the Subaru telescope on Maunakea, Hawaii.
