Ten Planets: Stories

Product Information

The magnetic fields of the other giant planets, measured at their surfaces, are roughly similar in strength to that of Earth, but their magnetic moments are significantly larger.

The magnetic fields of Uranus and Neptune are strongly tilted relative to the planets' rotational axes and displaced from the planets' centres.

The Second Discovery from the COCONUTS Program: A Cold Wide-orbit Exoplanet around a Young Field M Dwarf at 10. This process results in a collection of relatively substantial objects, each of which has either "swept up" or scattered away most of the material that had been orbiting near it.

Furthermore, deuterium is quite scarce, so the stage of deuterium burning does not actually last very long; unlike hydrogen burning in a star, deuterium burning does not significantly affect the future evolution of an object. As the planet nears apastron, its speed decreases, just as an object thrown upwards on Earth slows down as it reaches the apex of its trajectory. The situation was stable for four decades, but in the mid-1840s several additional asteroids were discovered ( Astraea in 1845; Hebe, Iris, and Flora in 1847; Metis in 1848; and Hygiea in 1849).There is great variation in the length of day between the planets, with Venus taking 243 days to rotate, and the giant planets only a few hours. The smallest object in the Solar System generally agreed to be a geophysical planet is Saturn's moon Mimas, with a radius about 3. The naming of planets differs between planets of the Solar System and exoplanets (planets of other planetary systems). Some of the larger trans-Neptunian objects, such as Quaoar, Sedna, Eris, and Haumea, [53] were heralded in the popular press as the tenth planet. The Kepler-11 system has five of its planets in shorter orbits than Mercury's, all of them much more massive than Mercury.
