The majority of the frames were acquired in gray scale with the probe's Wide-Angle Camera, while the close-up views of each planet were acquired in color using the Narrow-Angle Camera. [4] The image was acquired at a distance of approximately 40.11 AU (6.0 billion km; 3.7 billion mi) from Earth and approximately 32° above the ecliptic plane. [4]
Montage of planets and some moons that the two Voyager spacecraft have visited and studied. It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn.
The probe entered the interstellar medium on November 5, 2018, at a distance of 119.7 AU (11.1 billion mi; 17.9 billion km) from the Sun [5] and moving at a velocity of 15.341 km/s (34,320 mph) [4] relative to the Sun. Voyager 2 has left the Sun's heliosphere and is traveling through the interstellar medium, though still inside the Solar System ...
51 Pegasi b, officially named Dimidium / d ɪ ˈ m ɪ d i ə m /, is an extrasolar planet approximately 50 light-years (15 parsecs) away in the constellation of Pegasus.It was the first exoplanet to be discovered orbiting a main-sequence star, [2] the Sun-like 51 Pegasi, and marked a breakthrough in astronomical research.
Mariner 4 was the first space probe that needed a star for a navigational reference object, since earlier missions, which remained near either the Earth, the Moon, or the planet Venus, had sighted onto either the bright face of the home planet or the brightly lit target. During this flight, both the Earth and Mars would be too dim to lock onto.
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius.
The planet orbits the faint orange dwarf star [a] KOI-5715, which has a spectral type of K3V. [8] It is located approximately 2,964 light-years from Earth in the constellation of Cygnus. [ 9 ] The effective temperature of the star is roughly 5123 K, [ 1 ] relatively cooler than the Sun's temperature of 5780 K. [ 10 ] KOI-5715 is also smaller ...
Planet V, a planet thought by John Chambers and Jack Lissauer to have once existed between Mars and the asteroid belt, based on computer simulations. Various planets beyond Neptune: Planet Nine, a planet proposed to explain apparent alignments in the orbits of a number of distant trans-Neptunian objects. Planet X, a hypothetical planet beyond ...
