much of what is known about Neptune comes from the space probe Voyager II, which passed Neptune in 1989.

Neptune was found to have two narrow rings and other fainter ones, as well as six moons.

A year on Neptune is equal to almost 1656 Earth years. A Neptunian day is about 18 hours long.

What was the first planet discovered by the Voyager space probe?

Voyager did not discover any new planets. By the time Voyager was launched we already knew of all the planets in our solar system that we know of today. There were also two Voyager probes, not one. The first planet that either probe studied was Jupiter, which we had known for millennia. Voyager 1 flew by Jupiter in March 1979 while Voyager 2 flew by in July of the same year.

How can the mass of a planet be used to aid probes in space such as voyager?

Well, Voyager is now well beyond much useful gravitational influence of any of the solar system's planets. What we have learned is that planetary gravity wells can be used to provide a boost to passing spacecraft. Since Voyager most spacecraft to the outer planets spend some time in the inner system first, performing slingshots from one planet to the next to increase velocity. Each of these maneuvers robs a wee bit of the planet's angular momentum.

What planet were observed by Voyager the Pioneer Spacecraft?

Voyager 2 was launched first. It's trajectory was designed to take advantage of an unusually convenient alignment of the planets allowing the inclusion of Uranus and Neptune fly bys in the probe's mission. Voyager 1 was launched after its sister probe, but on a faster trajectory which enabled it to reach Jupiter and Saturn sooner at the expense of visiting the outer planets.
