Jupiter is the fifth planet from the Sun and the largest in the Solar System.It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun.
Jupiter was known to astronomers of ancient times. [1] The Romans named it after their god Jupiter . [ 2 ] When viewed from Earth , Jupiter can reach an apparent magnitude of −2.94, bright enough for its reflected light to cast shadows, [ 3 ] and making it on average the third-brightest object in the night sky after the Moon and Venus .

A super Jupiter has been spotted around a neighboring star by the Webb Space Telescope — and it has a super orbit. The planet is roughly the same diameter as Jupiter, but with six times the mass.
Jupiter is the fifth planet from the Sun and the largest in the Solar System.It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, and slightly less than one one-thousandth the mass of the Sun. Jupiter is the third brightest natural object in the Earth's night sky after the Moon and Venus, and it has been observed since ...
NASA's JIMO (Jupiter Icy Moons Orbiter), which was canceled in 2005, [76] and a European Jovian Europa Orbiter mission were also studied, [77] but were superseded by the Europa Jupiter System Mission. The Europa Jupiter System Mission (EJSM) was a joint NASA/ESA proposal for exploration of Jupiter and its
Mars and Jupiter are cozying up in the night sky for their closest rendezvous this decade. In reality, our solar system’s biggest planet and its dimmer, reddish neighbor will be more than 350 ...
