Planet UranusImage: Most planets rotate on an axis almost perpendicular to the ecliptic plane, but Uranus' axis is almost parallel to this plane. It seems to 'roll' in its orbit. Uranus is surrounded by its four main rings and 10 of its 27 known moons in this color view that uses ...
If we want understand the true nature ofAries, it will be helpful to look at the properties of its element – the fire. Fire emits heat and light what can be actually seen as its obvious description. But besides that, its most important feature isthat it always needs something to burn. ...
Ancient sky gazers applied the term planet to the seven celestial bodies that were observed to move appreciably against the background of the apparently fixed stars. These included the Sun and Earth’s Moon, as well as the five planets in the modern sense—Mercury, Venus, Mars, Jupiter, and...
Although smaller than Earth, Mercury is the most massive planet of all the telluric (or rocky) planets in the solar system, including Venus, Earth, and Mars. Due to its mass, Mercury has a stronger gravity than one would expect given its small size. Mercury's gravity is about 38% of ...
Planet, broadly, any relatively large natural body that revolves in an orbit around the Sun or around some other star and that is not radiating energy from internal nuclear fusion reactions. There are eight planets orbiting the Sun in the solar system.
Thus, Mars is a unique planet in the Solar System, the magnetosphere of which is formed by the interaction of the solar wind with the intrinsic magnetic field of the crust and with the ionosphere of the planet. The hypothesis that the Martian magnetosphere had a hybrid nature was put ...

frozen carbon dioxide at the poles). Meanwhile, while all four planets are the densest bodies in the solar system, Mars is actually much lighter than the other three – with about 60% the density of Earth and Venus. Earth is the only planet in the solar system with confirmed signs of ...
field of the Earth acts like a shield against the solar wind, leading to a magnetopause position many planetary radii away from the planet, in contrast to the situation at non or weakly magnetized planets such as Mars and Venus. ... H Nilsson - Springer Netherlands 被引量: 28发表: 2011...
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...
