    Nov. 30, 2018: This series of images from NASA's Juno spacecraft captures changing cloud formations across Jupiter's southern hemisphere. A cloud in the shape of a dolphin appears to be swimming through the cloud bands along the South South Temperate Belt.

    This sequence of images was taken between 2:26 p.m. and 2:46 p.m. PDT (5:26 p.m. and 5:56 p.m. EDT) on Oct. 29, 2018, as the spacecraft performed its 16th close flyby of Jupiter. At the time, Juno's altitude ranged from about 11,400 to 31,700 miles (18,400 to 51,000 kilometers) from the planet's cloud tops, at approximately 32 to 59 degrees south latitude.

    Citizen scientists Brian Swift and Seán Doran created this image using data from the spacecraft's JunoCam imager.

    The fifth planet from the Sun, and the most massive in our solar system, Jupiter has a long history surprising scientists—all the way back to 1610 when Galileo Galilei found the first moons beyond Earth. That discovery changed the way we see the universe. Explore Jupiter ›

    Ten Things to Know About Jupiter

    10 Things to Know About Jupiter


    The Grandest Planet

    Eleven Earths could fit across Jupiter’s equator. If Earth were the size of a grape, Jupiter would be the size of a basketball.


    Fifth Planet from Our Star

    Jupiter orbits about 484 million miles (778 million kilometers) or 5.2 Astronomical Units (AU) from our Sun (Earth is one AU from the Sun).


    Short Day/Long Year

    Jupiter rotates once about every 10 hours (a Jovian day), but takes about 12 Earth years to complete one orbit of the Sun (a Jovian year).

    Jupiter's Bands of Clouds


    What's Inside

    Jupiter is a gas giant and so lacks an Earth-like surface. If it has a solid inner core at all, it’s likely only about the size of Earth.


    Massive World, Light Elements

    Jupiter's atmosphere is made up mostly of hydrogen (H2) and helium (He).


    Worlds Galore

    Jupiter has more than 75 moons.


    Ringed World

    In 1979 the Voyager mission discovered Jupiter’s faint ring system. All four giant planets in our solar system have ring systems.


    Exploring Jupiter

    Nine spacecraft have visited Jupiter. Seven flew by and two have orbited the gas giant. Juno, the most recent, arrived at Jupiter in 2016.


    Ingredients for Life?

    Jupiter cannot support life as we know it. But some of Jupiter's moons have oceans beneath their crusts that might support life.


    Super Storm

    Jupiter's Great Red Spot is a gigantic storm that’s about twice the size of Earth and has raged for over a century.

    Juno's Eighth Close Approach to Jupiter

    Did You Know

    Did You Know?

    There are no rockets powerful enough to hurl a spacecraft into the outer solar system and beyond. In 1962, scientists calculated how to use Jupiter's intense gravity to hurl spacecraft into the farthest regions of the solar system. We've been traveling farther and faster ever since.

    Pop Culture

    Pop Culture

    The biggest planet in our solar system, Jupiter also has a large presence in pop culture, including many movies, TV shows, video games and comics. Jupiter was a notable destination in the Wachowski siblings’ science fiction spectacle Jupiter Ascending, while various Jovian moons provide settings for Cloud Atlas, Futurama, Power Rangers, and Halo, among many others. In Men in Black when Agent J—played by Will Smith—mentions he thought one of his childhood teachers was from Venus, Agent K—played by Tommy Lee Jones—replies that she is actually from one of Jupiter’s moons.

    Kid-Friendly Jupiter

    Jupiter is the biggest planet in our solar system. It's similar to a star, but it never got big enough to start burning.

    Jupiter is covered in swirling cloud stripes. It has big storms like the Great Red Spot, which has been going for hundreds of years.

    Jupiter is a gas giant and doesn't have a solid surface, but it may have a solid inner core about the size of Earth. Jupiter also has rings, but they're too faint to see very well.
