The correct answer is - it's mass.
Jupiter is the biggest planet in our Solar System, but only the biggest, also it has the biggest mass by far from all the planets. Because of its very big mass Jupiter has a very strong gravitational pull. The strong gravitational pull contributes to the attraction and keeping of lots of bodies that can not escape it, instead they revolve around the planet. These objects, or space bodies, that the gravitational pull of the planet managed to trap, became the moons, or rather natural satellites, of Jupiter.
El sol es probablemente la fuente más importante de energía renovable disponible hoy en día. Tradicionalmente, el sol ha proporcionado energía para prácticamente todas las criaturas vivientes en la tierra, a través del proceso de fotosíntesis, en el cual las plantas absorben la radiación solar y la convierten en energía almacenada para el crecimiento y el desarrollo.
