Full Moon Guide: October - November Winds in the outermost "lane" of Jupiter's Great Red Spot are accelerating — a discovery made possible by Hubble. The rover will be delivered to the Moon's surface in late VIPER is the first resource-mapping mission on the surface of another celestial body.
Full Moon Guide: September - October Full Moon Guide: August - September For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. The next full Moon goes by many names including the Buck Moon. Full Moon Guide: July — August The probe flew closer to Jupiter's largest moon, Ganymede, than any other spacecraft in more than two decades.

How many planets are in the solar system? Twelve new satellites were discovered in alone around Jupiter by researchers affiliated with the Carnegie Institution for Science thanks to recent advances in large digital cameras and astronomical techniques. In September , astronomers from the University of British Columbia identified 45 candidate moons with a diameter of over meters. The researchers only surveyed a tiny area of the sky though and when they extrapolated their data, they concluded that there could be more than of these tiny moons orbiting Jupiter.
These candidates are currently under investigation, which will take a lot of time since it takes quite a lot of telescope time to reliably verify their orbits.

The reason why Jupiter is such a moon magnet has a lot to do with its stupendous mass, equal to more than Earths. Jupiter, as well as other distant gas giants in the solar system such as Saturn and Neptune, has another ace up its sleeve. Not only does it have a very strong gravitational pull thanks to its mass, but it is also quite far away from the Sun. Meanwhile, Venus and Mercury, the two closest planets to the sun in the solar system, have no moons at all, while Earth has a measly one to speak of and Mars as two tiny satellites.
A cosmic body that is regularly round will have a more stable orbit than a potato-shaped one. Jupiter is almost perfectly round and that may have helped it capture some additional small satellites, especially in its lower orbit. These moons — Callisto, Io, Europan, and Ganymede — are often called Galilean moons in honor of Galileo Galilei, the Italian astronomer who first discovered them in
