Magnetosphere of Jupiter By 1973 the magnetic moment was known within a factor of two, whereas the tilt was correctly estimated at about 10°. The modulation of Jupiter's DAM by Io (the so-called Io-DAM) was discovered in 1964, and allowed Jupiter's rotation period to be precisely determined. The definitive discovery of the Jovian magnetic field occurred in December 1973, when the Pioneer 10 spacecraft flew near the planet. As of 2009 a total of eight spacecraft have flown around Jupiter and all have contributed to the present knowledge of the Jovian magnetosphere. The first space probe to reach Jupiter was Pioneer 10 in

Dora, Boots, and the aliens are required to find 4 colored space keys on different planets to unlock the Space Door to the Purple Planet. First, they find the Green Key on the slimy Green Planet. Next, they go to bubbly and musical Yellow Planet to find the Yellow Key. Then, they go to the windy and nebular Blue Planet to find the Blue Key.
