The total mass of the binary system is approximately 2.66 × 10 20 kg. The density of both the primary and the satellite is estimated at 1.24 g/cm 3, assuming that they have equal density. [10] [8] On the other hand, if the density or albedo of the satellite is lower than that of primary then the density of Varda will be higher up to 1.31 g/cm ...
Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations.
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from a distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System. [62]
6 April 1973 [2] Atlas SLV-3D Centaur-D1A [3] NASA: Flyby Successful [6] Closest approach towards Jupiter at 05:22 UTC on 3 December 1974. Flew by Callisto, Ganymede, Io and Europa . First probe to reach Saturnian system. Final contact was roughly at a distance of 6.5 billion km (43 AU; 4.0 billion mi) [7] 3 Voyager 2: Voyager 2: 20 August 1977 [2]
The Family Portrait, or sometimes Portrait of the Planets, is an image of the Solar System acquired by Voyager 1 on February 14, 1990, from a distance of approximately 6 billion km (40 AU; 3.7 billion mi) from Earth. It features individual frames of six planets and a partial background indicating their relative positions.

Its orbit has a perihelion (closest approach to the Sun) of 34.7 AU, an aphelion (farthest distance from the Sun) of 44.1 AU, an eccentricity of 0.12, and an inclination of 4° with respect to the ecliptic. [5] It is a plutino, being trapped in a 2:3 mean motion resonance with Neptune, similarly to dwarf planet Pluto, the largest known plutino.
