Its mass (1.989×1030 kg, approximately 330,000 times the mass of Earth) accounts for about 99.86% of the total mass of the Solar System.
A prominent result is the Great Red Spot, a giant storm that is known to have existed since at least the 17th century when it was first seen by telescope.
[It] has a prominent ring system that consists of nine continuous main rings and three discontinuous arcs, composed mostly of ice particles with a smaller amount of rocky debris.
[It] has a unique configuration among the planets because its axis of rotation is tilted sideways, nearly into the plane of its revolution about the Sun.
Weather patterns here are driven by the strongest sustained winds of any planet in the Solar System, with recorded wind speeds as high as 2,100 kilometres per hour (1,300 mph).
Estimates on how much longer the planet will be able to continue to support life range from 500 million years, to as long as 2.3 billion years.
With a mean surface temperature of 735 K (462 °C; 863 °F), [it] is by far the hottest planet in the Solar System.
[It] is the site of Olympus Mons, the second highest known mountain within the Solar System (the tallest on a planet), and of Valles Marineris, one of the largest canyons.
[It] is a satellite of Jupiter and the largest moon in the Solar System.
It is the only natural satellite known to have a dense atmosphere, and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found.
Because it has almost no atmosphere to retain heat, its surface experiences the greatest temperature variation of all the planets, ranging from 100 K (−173 °C; −280 °F) at night to 700 K (427 °C; 800 °F) during the day at some equatorial regions.
[It] is the outermost of the four Galilean moons of Jupiter. It orbits at a distance of approximately 1,880,000 km (26.3 times the 71,492 km radius of Jupiter itself).
With over 400 active volcanoes, [it] is the most geologically active object in the Solar System.
It is the brightest object in the sky after the Sun, although its surface is actually very dark, with a reflectance similar to that of coal.
Its surface is composed of water ice and is one of the smoothest in the Solar System. This surface is striated by cracks and streaks, whereas craters are relatively rare.
[It] is the largest moon of the planet Neptune, discovered on October 10, 1846, by English astronomer William Lassell.
Its discoverers and NASA initially described it as the tenth planet … [motivating] the International Astronomical Union define the term 'planet' for the first time. Under the IAU definition approved on August 24, 2006, [it] is a 'dwarf planet', along with objects such as Pluto.
Discovered in 1930, [it] was originally classified as the ninth planet from the Sun.
[It] is the largest of the moons of Uranus and ... is named after the queen of the fairies in Shakespeare's 'A Midsummer Night's Dream.'
It is the second largest and second most massive of the Uranian moons, and the ninth most massive moon in the Solar System.
It has no known satellites, which makes it unique among the largest Kuiper Belt objects and means that its mass can only be estimated.
[It] is the largest satellite of the dwarf planet Pluto.
It is the largest asteroid and the only dwarf planet in the inner Solar System.
[It] is the only short-period comet that is clearly visible to the naked eye from Earth, and thus the only naked-eye comet that might appear twice in a human lifetime.
On September 12, 2013, NASA announced that [it] had crossed the heliopause and entered interstellar space on August 25, 2012, making it the first manmade object to do so.
