    Backyard Worlds: Planet 9 is a NASA-funded citizen science project which is part of the Zooniverse web portal. [1] It aims to discover new brown dwarfs , faint objects that are less massive than stars, some of which might be among the nearest neighbors of the Solar System , and might conceivably detect the hypothesized Planet Nine .

    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.

    This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.

  8. Planet Nine - Wikipedia

    Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [4] [2] Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU).
