The planet formerly known as Pluto has a few companions orbiting it. Because of all the hoopla of the recent classification of Pluto as a dwarf planet, there has been a lot of attention focused around this celestial body. Within the past year, two more satellites have joined an older discovery bringing the number [...]

The planet Neptune is one of the planets that is furthest away from the sun. It is known mostly for the fact that it has an extremely cold surface, and a hot inner core. Neptune remains largely a mystery to be solved, and newer technology is in the makings, which will aid in this process. [...]

The Earth is hardly the only body in our solar system with volcanic activity. In fact, volcanic activity on Earth is actually quite tame when compared to the volcanic activity on a few other planets and quite a few moons in our Solar System. Of course, the Earth’s moon does not have a [...]

The planet Mercury has many mysteries of which the new spacecraft MESSENGER hopes to solve, but one of those mysteries is of particular interest to scientists. There are many eccentric features of the small planet closest to the Sun, but one theory suggests that the planet is shrinking. Slowly contracting in on itself [...]

According to one theory, Mercury was created after a giant asteroid collided with an even larger object about 4.5 billion years ago. This collision created the planet now known as Mercury and also shot a large amount of debris into space.
This idea that Mercury was the result of a collision was stemmed from the [...]

Pluto just celebrated its anniversary last year and commemorated it later in the year with a demotion from status as the ninth planet in our solar system to a significant dwarf planet. The discovery of Pluto was made seventy-six years ago and scientists still don’t really know much about this icy cold celestial body. [...]

Pluto is not just the name of the beloved Disney dog character. It is also the name of the once ninth planet of our solar system. Thanks to the recent reclassification of a planet, Pluto is now a significant dwarf planet instead. It lies on the edge of our solar system and is [...]

Many moons ago Uranus itself had not even been discovered; never mind all of the moons orbiting around it. The moons are still popping up! The Solar System seems to be losing planets, but the planets that still have their status as planets are gaining moons like there’s no tomorrow. Of course, [...]

In 2007 Japan plans to launch a space probe to Venus. This spacecraft will be the first of its kind. It will be unmanned, and is predicted to start orbiting Venus in 2009. Japan will be the third country to send a probe to Venus, following the United States and former Soviet Union. The Japanese [...]

The planet Mercury is the first in the Solar System line-up, meaning it is closet to the Sun.  It moves very quickly across the sky and so was named Mercury, which in Roman mythology was the god of commerce, travel, and thievery. 
Mercury is small and rocky and makes its trip around the Sun once every [...]
