The populations of comet-like bodies in the Solar system

In our classification scheme, a ‘comet’ has a perihelion q < 4 au, and so lies formally outside the zone of control of Jupiter. None the less, Jupiter dominates the lives of all the short-period comets. For example, 1P/Halley ...

Juno (spacecraft)
Juno is a NASA New Frontiers mission to the planet Jupiter. Juno was launched from Cape Canaveral Air Force Station on 5 August 2011 and will arrive on 4 July 2016. The spacecraft is to be placed in a polar orbit to study Jupiter's composition, gravity field, magnetic field, and polar magnetosphere. Juno will also search for clues about how the planet formed, including whether it has a rocky core, the amount of water present within the deep atmosphere, how its mass is distributed, and its deep winds, which can reach speeds of 618 kilometers per hour (384 mph).The spacecraft's name comes from Greco-Roman mythology. The god Jupiter drew a veil of clouds around himself to hide his mischief, but his wife, the goddess Juno, was able to peer through the clouds and see Jupiter's true nature.
