NASA had a choice of either doing a Pluto or Titan flyby; exploration of the moon took priority because it was known to have a substantial atmosphere. [6] [7] [8] Voyager 1 studied the weather, magnetic fields, and rings of the two gas giants and was the first probe to provide detailed images of their moons.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The planet was first seen in the original 1977 film Star Wars, and has to date featured in a total of seven Star Wars theatrical films, three live-action television series, and four animated series. It is the home planet of the protagonist of the original Star Wars Trilogy , Luke Skywalker , and of his father, Anakin Skywalker (who later became ...
A poster of the planets and moons visited during the Voyager program. The Voyager program is an American scientific program that employs two interstellar probes , Voyager 1 and Voyager 2 . They were launched in 1977 to take advantage of a favorable alignment of the two gas giants Jupiter and Saturn and the ice giants, Uranus and Neptune, to fly ...
There are 293 confirmed moons in our cosmic neighborhood. By studying these worlds, astronomers hope to learn about ancient asteroid collisions, space volcanoes, and the origins of life itself.
Pluto has roughly one-sixth the mass of the Moon, and one-third its volume. Pluto has a moderately eccentric and inclined orbit, ranging from 30 to 49 astronomical units (4.5 to 7.3 billion kilometres ; 2.8 to 4.6 billion miles ) from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its orbital distance of 39.5 AU (5.91 billion km ...
Outer Rim planet that is the homeworld of the Mandalorians torn by wars between Mandalorians and Jedi and eventually purged by the Empire, scattering the few Mandalorians throughout the galaxy (including Bo-Katan). Mandalore has one moon, Concordia, which is fully inhabited. [84] Star Wars: The Clone Wars: 2010 TV series Mapuzo: Obi-Wan Kenobi ...
The four giant planets have planetary rings, thin discs of tiny particles that orbit them in unison. [47] As a result of the formation of the Solar System, planets and most other objects orbit the Sun in the same direction that the Sun is rotating. That is, counter-clockwise, as viewed from above Earth's north pole. [48]
