What is the mass of Mars in kilograms? What planet is between Jupiter and Uranus? What are the distinguishing characteristics of Venus? What constellation is Venus in? What is the composition of the atmosphere of Venus? What is unusual about the rotation of Venus?
If a satellite has a mass on earth of 50 kg, what is its mass on a planet where the gravitational constant is 1/10 its value on Earth and the planet is 1 million km from Earth? A 1.0kg mass weighs 9.8n on Earth's surface, and the radius of the Earth is roughly 6.4x10^6m. W...
Of these planets, the most massive isJupiter, which is also the second most massive object in the solar system after the sun. Jupiter has a mass of 4.2 × 1027lbs (1.9 × 1027kgs),according to NASA. This means the sun is almost exactly three orders of magnitude, or 1,000 times, mor...
Among the 100 or so extrasolar planets discovered to date, the most bizarre are the dozen or so Jupiter-mass planets that orbit their parent stars with periods between three and seven days. These so-called ``hot Jupiters'' offer the most immediate chances for direct detection and ...
A planet does not have to have a moon to be a planet. Pluto has numerous moons but is not a planet in the same sense as Earth. Also, Mercury has no moons but is a fully-fledged planet like Earth. All the gas planets, including Jupiter and Neptune, have rings of dust. Jupiter's ...
Whatever is not drawn into planets ends up dissipated and evaporated by solar, wind and radiation from nearby stars. So basically, a baby Jupiter would run out of gas before it grew up. But the disk instability theory, well, the timing is right. That process is fast enough to finish befo...
The relationship to find the speed of Jupiter before the mass of the sun is determined through the equilibrium condition between the gravitational force and the centripetal force. The gravitational force is defined as the product between the m...
But planetologists have discovered that Earth's very presence in this Goldilocks zone is itself due to an amazing stroke of luck. When the Solar System was still young, this zone came close to being taken over by the planet Jupiter.但行星学家发现，地球出现在这片“宜居带”本身就有惊人的...
ask the gravitational force of a planet when they want to know the gravity on a planet. For example, the gravity on Jupiter is {eq}24.79 m/s^2 {/eq}. Both the gravity and the gravitational force of a planet are influenced by the mass of a planet. Jupiter has a mass of {eq}...
The Earth's orbit defines the length of a year. 2 Jupiter Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, but slightly less than...
