Freebase

  1. Iapetus

    Iapetus, occasionally Japetus, is the third-largest natural satellite of Saturn, and eleventh-largest in the Solar System. Compared to Earth's moon, its radius is about 42% and its density is about 32.5% resulting in a mass of about 2.5% of Earth's moon. Iapetus is best known for its dramatic 'two-tone' coloration, but discoveries by the Cassini mission in 2007 have revealed several other unusual physical characteristics, such as an equatorial ridge that runs about halfway around the moon.

Sample Sentences & Example Usage

  1. Ryan Cloutier:

    Ultimately, we found that Jupiter is capable of ejecting the fifth giant planet while retaining a moon with the orbit of Callisto, on the other hand, it would have been very difficult for Saturn to do so because Iapetus would have been excessively unsettled, resulting in an orbit that is difficult to reconcile with its current trajectory.

  2. Matija Cuk:

    But that fact allows us to use computer simulations to tease out the history of Saturn ’s inner moons, doing so, we find that they were most likely born during the most recent 2 percent of the planet ’s history. Related : Saturn's largest moon Titan is bursting with color Researchers had long thought Saturn ’s rings were as old as the planet itself. But that thinking changed in 2012, when French astronomers found that tidal effects – the gravitational interaction of the inner moons with fluids deep in Saturn ’s interior – are causing them to spiral to larger orbital radii comparatively quickly. The implication, given their present positions, is that these moons, and presumably the rings, are not so old. That still did n’t answer exactly when they were born. Cuk and his team turned to results from NASA ’s Cassini mission, which has observed ice geysers on Saturn ’s moon Enceladus. Assuming that the energy powering these geysers comes directly from tidal interactions and that Enceladus ’ level of geothermal activity is more or less constant, then the tides within Saturn are quite strong. According to the team ’s analysis, these would move the satellite by the small amount indicated by the simulations in only about 100 million years.
