Sample Sentences & Example Usage

  1. Tushar Mittal:

    If the moon broke apart at 1.2 Mars radii, about 680 kilometers above the surface, it would form a really narrow ring comparable in density to that of one of Saturn’s most massive rings, over time it would spread out and get wider, reaching the top of the Martian atmosphere in a few million years, when it would start losing material because stuff would keep raining down on Mars.

  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.
