Today, the world decides whether Pluto should be a planet in our solar system or otherwise. Below are interesting facts about other planetary objects.

Mercury, Mars, Earth and Venus are the first four planets of our currently known solar system. There is much debate on Pluto whether to consider it as a planet or a rounded asteroid.

The giant planets are separated by an asteroid belt right after Mars. If Jupiter had not stop spinning too fast it might had been another star. Most of the known galaxies are populated by binary stars.

The sun account more than 99 percent of the solar system's mass. Theory states that about 74 percent of the sun's mass is hydrogen, 25 percent helium and other heavy elements. It's radius is 110 times larger than earth.

In this picture Jupiter is one pixel in size and earth is invisible to this scale. Sirius is the brightest star in the nighttime sky. Those living in the northern part of the earth can see it. Pollux is located about 33.7 light-years from our sun and it is the brightest star in the gemini constellation. Arcturus is the fourth brightest star in the earth's night sky and located in the Ursa Major constellation.

Jupiter is now invisible in this scale. Rigel is the brightest star in the orion constellation, approximately 733 light-years from our sun and classified as a super giant star. Aldebaran is visible in the taurus constellation and a binary star system with a distance of 65.1 light-years from the sun. Betelgeuse is a super red giant and about 427 light-years away from our sun and visible in the orion constellation. Antares is classified as class M super red giant with is approximately 600 light-years away from earth.
