The presence of a Jupiter-mass companion to the star 51 Pegasi is inferred from observations of periodic variations in the star's radial velocity. The companion lies only about eight million kilometres from the star, which would be well inside the orbit of Mercury in our Solar System. This ...

s5.52 grams per cubic cm—coupled with its large dimensions and mass and short rotation period. The low density and large mass indicate that Jupiter’scompositionand structure are quite unlike those of Earth and the other innerplanets, a deduction that is supported by detailed investigations of ...

The current exoplanet census contains5,832 confirmed candidates, with more than 7,500 still awaiting confirmation. Of those that have been confirmed, most have been gas giants ranging from Neptune-like bodies (1992) to those similar to or many times the size and mass of Jupiter and Saturn (...
2. Jupiter's mass is more than twice than that of all the other planets in the solar system combined. 相关知识点: 试题来源: 解析 答案见上2. that 句意:木星的质量是太阳系中其他所有行星质量总和的两倍 多。在比较状语从句中,用that指代可数名词单数和不可数名词。 此处that指代mass。
mass one-thousandth that of the Sun but is two and a half times the mass of all the other planets in our Solar System combined. Jupiter is classified as a gas giant along with Saturn, Uranus and Neptune. Together, these four planets are sometimes referred to as the Jovian or outer ...
Among the Giant planets, Jupiter is the most massive and also the closest to the Sun; it orbits at 5.2 AU from the Sun. Its mass is 318 times the terrestrial mass and its diameter is 11 times the terrestrial one, which corresponds to a density of 1.31 g/cm3. As the other giant plan...
The planet Jupiter has several amazing features that set it apart from other planets in the solar system. This gas giant is a complex system on its own. Impressive size: Jupiter is the largest planet in the solar system. Its mass is more than twice that of all the other planets combined...
Still, the spot remains the most prominent characteristic of the solar system's largest planet, a gargantuan ball of gas -- mostly hydrogen and helium -- 11 times the diameter of Earth with more than twice as much mass as all the other planets combined. Monday'...
