Space Cool Facts That You Didn’t Know

There are nine known planets in the space. We live on planet earth. Between planets, there is an empty area called Space. There is no matter in the space.  However, there are several different objects in the space that revolve around the planets.

In this article, we have collected the top cool facts about space that you need to know.

We Always See The Same Side Of The Full Moon

The moon rotates at the same rate that it orbits on its axis. The movement is called the tidal locking or synchronous rotation.  Therefore, only one side of the full moon is visible at all the time.  

The sun directly illuminates its light to the moon. Cyclically differing moon positions bring the lunar phases.

The Longest Possible Eclipse Is Expected To Be 7.31 Minutes

There has never been such a long Eclipse. Scientist predicts that the longest total solar eclipse will happen on July 16, 2186. This will be the longest eclipse since 4000 BCE. The Eclipse will last for exactly 7.31 minutes.

During that time, the eclipse paths are expected to sweep through Guyana, Venezuela, and Colombia.

Halley’s Comet is a periodic and most famous comet. It rotates the earth and is visible after every 75 years.

In one’s lifetime, it’s only possible to see the comet twice.

The comet is expected to pass the earth again in 2061. Last time it was seen it was in 1986.

Edmund Halley initially recorded Halley’s comet in the year 1682. It appeared again in 1758, 1835, 1910, and 1986.

There Is No Sound In Space

Sound to exist; it needs to be transmitted by a medium. In space, there are no molecules. It’s an empty vacuum between planets and stars. Therefore, there is no medium for the sound wave to travel through.  If you were to shout, no one would hear you in space.

Over 500 Large Meteorites Hit The Earth Each Year

Every day, 36 to 166 meteors fall on Earth per million square kilometers. Over the entire earth surface that translates to 18,000 to 84,000 meteorites per year. The meteorites are larger than 10 grams.  Most meteors are small. Over 500 large meteorites fall yearly.

The Sun Is A Star

Sun is considered to be the largest star near the face of the solar system. It’s almost a perfect hot plasmasphere. It has internal convective motion. Through a dynamo process, the sun generates a magnetic field.

The sun is the major source of light and energy on planet earth.

The moon is the second largest source of light to the earth. It revolves and orbits the earth through its axis. The moon rotates the earth at a speed of 2,288 (3,683) miles per hour. It travels a distance of 1,423,000 miles around the earth surface.

Approximately 27.32 days are spent by the moon to orbit the entire earth. The moon takes a synodic month to reach the same visual phase. The synodic month varies throughout the year. The average days are 29.53 days.

The cool facts about the moon determine the days of the month.


Space is a fantastic creation. Astronomers have tried to uncover the mysteries of space, but our human knowledge is limited. From vacuum space to falling comets no one seems to have an explanation of everything that happens in the space.
