It is surrounded by an extremely thin atmosphere composed of carbon dioxide and probably molecular oxygen. Named after Paisphae, which has a mean radius of 30 km, these satellites are retrograde, and are also believed to be the result of an asteroid that was captured by Jupiter and fragmented due to a series of collisions. Many are believed to have broken up by mechanical stresses during capture, or afterward by collisions with other small bodies, producing the moons we see today. Jupiter's Racing Stripes. If it does, then Europa may have an ocean with more than twice as much liquid water as all of Earth's oceans combined.

Retrieved 8 January Other evidence comes from double-ridged cracks on the surface. Those that are grouped into families are all named after their largest member. Ganymede has a much weaker tidal force, and thus weaker tidal heating than Europa and Io. The other moons, in the majority of astronomical literature, were simply labeled by their Roman numeral i. Its surface features include large craters and ridges. The other moons were simply labeled by their Roman numeral e. Jupiter also has the strongest magnetic field of any planet, so anything passing near it, such as an asteroid, is either destroyed by gravitational tides or captured into its orbit. The moons of Jupiter are so numerous and so diverse that they are broken down into several groups. The case for Europa's subsurface ocean comes from the strong probability of tidal heating, melting the ice under the surface. In fact, it was not until the 20th century, and with the aid of telescopic photography and other refinements, that most of the Jovian satellites began to be discovered. Not necessarily. With a mean radius of 23 km, Carme is the largest member of a family of Jovian satellites which have similar orbits and appearance uniformly red , and are therefore thought to have a common origin. The Moons of Jupiter Writer The frequency of these sulfuric eruptions has filled in almost all of the impact craters and left Io with one of the youngest looking surfaces in the solar system. Io is the most volcanically active body in the solar system. Tidal flexing that allows water to well up and build ridges may create these cracks. These orbits are also nearly circular and have a low inclination, meaning they orbit close to Jupiter's equator. Metis is the closest moon to Jupiter at a distance of , km. In Bagenal, F. Barnard observed Amalthea in The moons of Jupiter are listed below by orbital period. The level of Ganymede's tidal heating could not provide enough heat to make an ocean of liquid water.

The surface of Ganymede shares many similarities with Europa. Thebe aka. Its outstanding characteristic is that it is the only moon to have its own magnetic field. These photos, taken by the Galileo spacecraft, show what appears to be icebergs stuck in a layer of ice. Jupiter's regular satellites are believed to have formed from a circumplanetary disk, a ring of accreting gas and solid debris analogous to a protoplanetary disk. The Planetary Science Journal.

By the time Voyager space probes reached Jupiter around , 13 moons had been discovered, while Voyager herself discovered an additional three — Metis, Adrastea, and Thebe. These moons all have prograde orbits, meaning they orbit in the same direction as Jupiter's rotation. The next full Moon will be on Thursday afternoon, Oct. Retrieved 2 August Jupiter's largest moon, Ganymede, is larger than Mercury while the other three are larger than Pluto. The other moons were simply labeled by their Roman numeral e. Europa has a high degree of reflectivity, making it among the brightest moons in the solar system. Callisto , the fourth and farthest of the Galilean moons from Jupiter, is the most heavily cratered object in the solar system. Europa might be the best place to look for environments where life could exist. The next full Moon will peak after midnight on Wednesday morning, Sept. Its surface features also include large craters and high mountains — some of which are comparable to the size of the moon itself. Earth only has one moon because it lacks the strong gravitational field and mass necessary to hold another satellite in orbit. Aside from tidal heating, we are not sure where sufficient heat would come from to melt the ice. The Moons of Jupiter Read Online Cyclones of Color at Jupiter's North Pole.

Cast | 608 pages | 24 Oct 2016 | St Martin's Press | 9781250125781 | English | New York, United States How Far is the Moon? | Moon Facts Moons and rings are among the most fascinating objects in our solar system. Before the Space Race of the s, astronomers knew that Earth, Mars, Jupiter, Saturn, Moon Chosen, and Neptune had moons; at that time, only Saturn was known to have rings. With the advent of better telescopes and space-based probes that could fly to distant worlds, scientists began to discover many more moons and rings. Moons and rings are typically categorized as "natural satellites" that orbit other worlds. It's not even the largest one. Jupiter's moon Ganymede has that honor. And in addition to the moons orbiting planets, nearly asteroids are known to have moons of their own. The technical term is "natural satellite", which differentiates them from the man-made satellites launched into space by space Moon Chosen. There are dozens of these natural satellites throughout the solar system. Different moons have different origin stories. However, Mars's moons Moon Chosen to be captured asteroids. Moon materials range from rocky material to icy bodies and mixtures of both. Earth's moon is made of rock Moon Chosen volcanic. Mars's moons are the same material as rocky asteroids. Jupiter's moons Moon Chosen largely icy, but with rocky cores. The exception is Io, which is a completely rocky, highly volcanic world. Saturn's moons are mostly ice with rocky cores. Its largest moon, Titan, is predominantly rocky with an icy surface.

  • The Moons of Jupiter – Orbital Synchrony 3
    The Moons of Jupiter – Orbital Synchrony 3 The figure above shows the orbits of many of Jupiter's numerous satellites. Each of these ‘moons’ orbits Jupiter in a different number of days. The image to the right shows the appearance of one of Jupiter’s moons Callisto. The orbit periods of many of the moons have simple relationships between them. When Jupiter’s moon Ganymede orbits 1/2 way around Jupiter, Jupiter's moon Europa orbits Jupiter once. When Jupiter’s moon Leda orbits Jupiter once, Ganymede orbits Jupiter 34 times. When Jupiter's moon Leda orbits Jupiter five times, the more distant moon Thelxinoe orbits Jupiter twice. When Leda orbits Jupiter three times, the moon Kalyke orbits Jupiter once. Example: 1/2 x Ganymede = 1 x Europa, so in the time it takes Europa to go once around Jupiter, Ganymede goes only ½ way around in its orbit. Problem 1 - How many times does Ganymede orbit Jupiter in the time it takes Europa to orbit six times? Problem 2 – How many times does Leda orbit Jupiter in the time it takes Ganymede to orbit Jupiter 6 times? Problem 3 - How many orbits will Thelxinoe have to complete around Jupiter before Kalyke orbits exactly five times? Space Math http://spacemath.gsfc.nasa.gov Answer Key 3 Problem 1 - How many times does Ganymede orbit Jupiter in the time it takes Europa to orbit six times? Answer: The information says that Europa orbits once when Ganymede orbits 1/2 times, so 1 x Europa = 1/2 x Ganymede and so 2 x Europa = 1 x Ganymede.

Gravitational capture can be used to explain the existence of the irregular satellites of giants planets. However, it is only the first step since the gravitational capture is temporary. Therefore, some kind of non-conservative effect is necessary to to turn the temporary capture into a permanent one. In the present work we study the effects of Jupiter mass growth for the permanent capture of retrograde satellites. An analysis of the zero velocity curves at the Lagrangian point L1 indicates that mass accretion provides an increase of the confinement region (delimited by the zero velocity curve, where particles cannot escape from the planet) favoring permanent captures. Adopting the restricted three-body problem, Sun-Jupiter-Particle, we performed numerical simulations backward in time considering the decrease of M . We considered initial conditions of the particles to be retrograde, at pericenter, in the region 100 R a 400 R and 0 e 0:5. The results give Jupiter’s mass at the X moment when the particle escapes from the planet.
