The planets as known during classical antiquity: the Moon, the Sun, Mercury, Venus, Mars, Jupiter, and Saturn. Earth analog: A planet or even a superhabitable planet with conditions to be compared with those found on Earth. Teegarden b and c, KOI-4878.01 (unconfirmed) Jupiter analog
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
Size of Jupiter compared to Earth and Earth's Moon Jupiter is about ten times larger than Earth ( 11.209 R 🜨 ) and smaller than the Sun ( 0.102 76 R ☉ ). Jupiter's mass is 318 times that of Earth; [ 2 ] 2.5 times that of all the other planets in the Solar System combined.
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
The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
Just one day before opposition, Jupiter will be around 367 million miles away from the Earth, the closest the two planets have been in 59 years, according to NASA. The last time that Jupiter was ...
"Inferior planet" refers to Mercury and Venus, which are closer to the Sun than Earth is. "Superior planet" refers to Mars, Jupiter, Saturn, Uranus, and Neptune (the latter two added later), which are further from the Sun than Earth is. The terms are sometimes used more generally; for example, Earth is an inferior planet relative to Mars.
Jupiter on Saturday will shine at its brightest for the year, as Earth’s orbit swings our planet between Jupiter and the sun. Weather permitting, the gas giant will not only be brighter than ...
