However, the equatorial escape velocity, nearly 36 km/s, is much higher than that of Earth. [38] Saturn is the only planet of the Solar System that is less dense than water—about 30% less. [39] Although Saturn's core is considerably denser than water, the average specific density of the planet is 0.69 g/cm 3, because of the
For instance, honey has a much higher viscosity than water. ... Au 1100 5.130 1200 4.640 1300 4.240 Copper: Cu 1100 3.92 1200 3.34 1300 2.91 1400 2.58 1500 2.31
This is because the distance between Earth and the Sun is not fixed (it varies between 0.983 289 8912 and 1.016 710 3335 au) and, when Earth is closer to the Sun , the Sun's gravitational field is stronger and Earth is moving faster along its orbital path. As the metre is defined in terms of the second and the speed of light is constant for all ...
Titania (/ t ə ˈ t ɑː n i ə, t ə ˈ t eɪ n i ə /), also designated Uranus III, is the largest moon of Uranus.At a diameter of 1,578 kilometres (981 mi) it is the eighth largest moon in the Solar System, with a surface area comparable to that of Australia.
It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Its diameter is eleven times that of Earth , and a tenth that of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm ), with an orbital period of 11.86 years .
570 Gm (3.8 au) – length of the tail of Comet Hyakutake measured by Ulysses; the actual value could be much higher; 590 Gm (3.9 au) – diameter of the Pistol Star, a blue hypergiant star [183] 591 Gm (4.0 au) – minimum distance between the Earth and Jupiter; 780 Gm (5.2 au) – average distance between Jupiter and the Sun
The Sun's corona is much hotter (by a factor from 150 to 450) than the visible surface of the Sun: the corona's temperature is 1 to 3 million kelvin compared to the photosphere's average temperature – around 5 800 kelvin. The corona is far less dense than the photosphere, and produces about one-millionth as much visible light.
Assuming the Jovian orbit of 5.5 AU as the star radius, the inner shell would extend roughly 50 to 150 stellar radii (~300 to 800 AU) with the outer one as far as 250 stellar radii (~ 1,400 AU). The Sun's heliopause is estimated at 100 AU, so the size of this outer shell would be almost fourteen times the size of the Solar System.
