Astronomers have discovered something they've called a "watery alien world" - a planet completely covered by ocean.

Located in the solar system of a star about 100 light-years away from earth, where a year lasts 11 days, the planet is located in the so-called "Goldilocks Zone" or "Habitable Zone", where its temperature would be just right for the formation of liquid water on the surface.

Like Earth, this planet would have the ability to store liquid water, as its distance from its 'sun' makes it possible for it to be neither too hot nor too cold.

Named TOI-1452 b, the planet is slightly larger in size and mass than Earth, but because of its lower density compared to Earth, scientists think it may be covered by a thick layer of water.

Planets with oceans are of particular interest to astronomers and space enthusiasts, as they are thought to be strong candidates for planets where life may have originated or even survive.

'The best candidate for the ocean planet'

Astronomers working on the study have called TOI-1452 b one of the best ocean planet candidates discovered so far.

"TOI-1452 b is one of the best exoplanet candidates we've found to date," said Charles Cadieux, a doctoral student at the University of Montreal and a member of the Institute for Exoplanet Research.

"Its radius and mass suggest a much lower density than would be expected for a planet that is essentially composed of metal and rock, like Earth."

TOI-1452 b is thought to be rocky like Earth, but its lower-than-expected density is believed to be due to a much larger amount of water than we have on Earth.

While 70% of planet Earth's surface is covered in water, water actually makes up less than 1% of our planet's mass.

The astronomers' analysis revealed that up to 30% of TOI-1452 b's mass may consist of water.

This is a similar proportion to some of the moons found in our Solar System, such as Jupiter's Ganymede and Callisto, and Saturn's Titan and Enceladus.

Publishing their findings in The Astronomical Journal, the team is already planning follow-up studies with the most powerful telescope in history.
