there could eventually be life in Ganymede there is underground ocean the surface is frozen ice but the only bad thing is to far away from the sun and also it dose not have bacteria
Same as on Jupiter. About 12 Earth years.
Ganymede experiences the same mild temperature change as Jupiter as it orbits the sun. However due it is negligible atmosphere of 0.1 Pa, and surface of water ice, it's is restricted as to what it can experience in the way of seasonal change.
The orbital period of Ganymede around Jupiter is 7.154 Earth days, or about one Earth week.

The Sun. The next star is 4.3 light years away. If you mean "what stars appear to be near Ganymede in the sky", it varies; Jupiter (and therefore Ganymede) moves relative to the stars so you'd need to consult an ephemeris to see what the current position is.
'Weather' would be a very loose term on the surface, since the atmosphere has a pressure of only 0.1 Pa. There would be temperature changes, but don't expect to see storms, winds, rains or anything of the sort. Meteor showers, maybe?
It Is Made Up of A Thin Layer Of Oxygen That Is To Thin to Support Living Organisms.
Because it has the highest albedo, or it's ability to diffuse light from it's surface, combined with the fact that it is the largest moon of Jupiter.
Yes! Ganymede has winds it has plasma winds that were researched by galilelo and recorded by him
Ganymede's year is the same as Jupiter's, since it is a satellite of that planet. However, it orbit's Jupiter every 7 days, 3 hours, and 42 minutes, and 33.2 seconds.
Ganymede is a natural satellite of Jupiter and the largest natural satellite in the Solar System. Completing an orbit in roughly seven days, it is the seventh satellite and third Galilean satellite from Jupiter. Ganymede participates in a 1:2:4 orbital resonance with the satellites Europa and Io, respectively. It is larger in diameter than the planet Mercury but has only about half its mass. Ganymede is composed primarily of silicate rock and water ice. It is a fully differentiated body with an iron-rich, liquid core. A saltwater ocean is believed to exist nearly 200 km below Ganymede's surface, sandwiched between layers of ice. Its surface comprises two main types of terrain. Dark regions, saturated with impact craters and dated to four billion years ago, cover about a third of the satellite. Lighter regions, crosscut by extensive grooves and ridges and only slightly less ancient, cover the remainder. The cause of the light terrain's disrupted geology is not fully known, but was likely the result of tectonic activity brought about by tidal heating. Ganymede is the only satellite in the Solar System known to possess a magnetosphere, likely created through convection within the liquid iron core. The meager magnetosphere is buried within Jupiter's much larger magnetic field and connected to it through open field lines. The satellite has a thin oxygen atmosphere that includes O, O2, and possibly O3 (ozone). Atomic hydrogen is a minor atmospheric constituent. Whether the satellite has an ionosphere to correspond to its atmosphere is unresolved. Ganymede's discovery is credited to Galileo Galilei, who observed it in 1610. The satellite's name was soon suggested by astronomer Simon Marius, for the mythological Ganymede, cupbearer of the Greek gods and Zeus's beloved. Beginning with Pioneer 10, spacecraft have been able to examine Ganymede closely. The Voyager probes refined measurements of its size, while the Galileo craft discovered its underground ocean and magnetic field. A new mission to Jupiter's icy moons, the Europa Jupiter System Mission (EJSM) is proposed for a launch in 2020.
