1 dzień temu · Entering a Hohmann transfer orbit from Earth to Jupiter from low Earth orbit requires a delta-v of 6.3 km/s, which is comparable to the 9.7 km/s delta-v needed to reach low Earth orbit. Gravity assists through planetary flybys can be used to reduce the energy required to reach Jupiter.
2 dni temu · It takes nearly 12 Earth years to orbit the Sun, and it rotates once about every 10 hours, more than twice as fast as Earth; its colourful cloud bands can be seen with even a small telescope. It has a narrow system of rings and 92 known moons, one larger than the planet Mercury and three larger than Earth’s Moon.

5 dni temu · In fact, the true rotation period of Jupiter is System III (9 hours 55 minutes 29 seconds). This is the period of rotation of Jupiter’s magnetic field, first deduced from Earth-based observations at radio wavelengths ( see below Radio emission) and confirmed by direct spacecraft measurements.
