Water is thought to be one of the unique characteristics of the earth. Recently, however, this idea was proven wrong. It seems that water could be a common factor with many other planets.
Asteroids
Over 500 light-years away, a white dwarf star SDSS J1242+5226, found in the Ursa Major constellation, is leaving scientists in awe. Researchers at the University of Warwick suggest that this star has the volume of 30-35% of the earth’s water. How water arrived at this star is significant. Scientists believe a large asteroid provided the planet’s water supply. This asteroid is thought to have been about the size of Ceres in our own solar system.
