Time-lapse sequence from the approach of Voyager 1 to Jupiter in 1979, showing the motion of atmospheric bands, and the circulation of the Great Red Spot. The momentary black spots are shadows cast by Jupiter's moons. Jupiter's Great Red Spot rotates counterclockwise, with a period of about 4.5 Earth days, [24] or 11 Jovian
New observations of Jupiter’s Great Red Spot captured by the Hubble Space Telescope show that the 190-year-old storm wiggles like gelatin and shape-shifts like a squeezed stress ball.
The storm measured about 24,200 miles (about 39,000 kilometers) at its longest point, according to data from 1879, but it has been shrinking and becoming more rounded over time, and is now about ...

Two other space probes observed the impact; the Ulysses spacecraft, primarily designed for solar observations, was pointed towards Jupiter from its location 2.6 AU (390 million km; 240 million mi) away, and Voyager 2, which was then 44 AU (6.6 billion km; 4.1 billion mi) from Jupiter, was programmed to look for radio emissions in the 1–390 ...

The closest in the past 1,000 years was in 1761, when Mars and Jupiter appeared to the naked eye as a single bright object, according to Giorgini. Looking ahead, the year 2348 will be almost as close.
The "Mars problem" is a conflict between some simulations of the formation of the terrestrial planets which end with a 0.5–1.0 M E planet in its region, much larger than the actual mass of Mars: 0.107 M E, when begun with planetesimals distributed throughout the inner Solar System. Jupiter's grand tack resolves the Mars problem by limiting ...
