For example, during the opposition of 17 December 2002, Saturn appeared at its brightest due to the favorable orientation of its rings relative to the Earth, [178] even though Saturn was closer to the Earth and Sun in late 2003. [178] From time to time, Saturn is occulted by the Moon (that is, the Moon covers up Saturn in the sky). As with all ...
They are named "great" for being by far the rarest of the conjunctions between naked-eye planets [1] (i.e. excluding Uranus and Neptune). The spacing between the planets varies from conjunction to conjunction with most events being 0.5 to 1.3 degrees (30 to 78 arcminutes, or 1 to 2.5 times the width of a full moon).

The Moon will also join the line-up on April 23, with a fifth planet – Mercury – becoming visible from June 24. Despite appearing from Earth to be lined up, the planets will not actually be ...
Earth–Moon L 1 and L 2: NASA: Mission consists of two spacecraft, which were the first spacecraft to reach Earth–Moon Lagrangian points. Both moved through Earth–Moon Lagrangian points, and are now in lunar orbit. [34] [35] WIND: Sun–Earth L 2: NASA: Arrived at L 2 in November 2003 and departed April 2004. Gaia Space Observatory: Sun ...
A historic extraterrestrial sky—Earthrise, the Earth viewed from the Moon.Taken by Apollo 8 astronaut William Anders while in lunar orbit, December 24, 1968.. In astronomy, an extraterrestrial sky is a view of outer space from the surface of an astronomical body other than Earth.
NASA released a series of stunning images of Saturn's icy moon, Dione, from the Cassini spacecraft's final close flyby. The craft, which has been exploring Saturn and its moons since 2004, passed ...
Titan orbits Saturn at 20 Saturn radii or 1,200,000 km above Saturn's apparent surface. From Titan's surface, Saturn, disregarding its rings, subtends an arc of 5.09 degrees, and if it were visible through the moon's thick atmosphere, it would appear 11.4 times larger in the sky, in diameter, than the Moon from Earth, which subtends 0.48° of arc.
