5 things we bet you didn't know about outer space

The outer space and its myriad secrets have always fascinated us. And if you think that all the sci-fi movie makers have taken their imagination a bit too far with the weird happenings in their films, let us tell you that in this case, fact is definitely stranger than fiction. Here are five bizarre facts that prove our point.

• Since its discovery, Neptune has only completed one orbit around the Sun. The planet takes 165 years to complete one full orbit around the Sun. Since it was discovered only in 1846, Neptune finished its first full post-discovery orbit only in 2011.

• While the rest of us are struggling to lose weight, the Sun loses a billion kilos per second. This is attributed to the tremendous heat generated in the Sun’s upper atmosphere, which causes the particles to speed out into space as part of the solar wind.

• The Moon is not round in shape or blessed with a smooth surface, contrary to popular belief. It is, in fact, shaped like a lemon, with several bulges all over.

• According to research by Yale University, there may be a planet made out of diamonds. According to the study, a rocky planet called 55 Cancri e may have a surface made up of graphite and diamond. The planet has a radius twice as much as Earth’s, and its mass eight times greater.

• The footprints on the moon will remain intact as it has no atmosphere. A lack of atmosphere means that there is no wind to erode the surface.
