A ‘super Earth’ has been discovered near one of the oldest stars in the galaxy.

The planet, called TOI-561b, is approximately 50 per cent larger than Earth, and it orbits around its star astonishingly quickly: in just one of our days, it has seen two years.

One theory is that this sudden accretion of material on TOI-561b is the result of a "hit and miss"' object flying past the old red giant planet, which was discovered only two years ago.

That's because it had struck before, burning through its atmosphere and destroying that as well as the surrounding planets.

"This planets rapid undulation around the star is not possible in the current models of planet formation, which use only flat disk and elliptical orbits with a distancing factor of less than 40,"wrote Orsa Snir of the CfA.


In "a paper entitled 'Tug of War between Super-Earths and Their Asteroids', now in press, Dr Tyler Tingay of Harvard University writes:

"Now that the Oort cloud has been probed, the authors argue that usua­ble planets in the Oort cloud should be less prone to planet formation via accretion than either Jupiter or Saturn — meaning that potentially habitable worlds may all come from rogue worlds."

"This can be argued effectively by pointing out that more of the Oort cloud than of the gravity-dominated disk planets can be explained by a rogue planet relatively close to the star, because it has no tidal influence from the star, "the result of Phil Plait, creator of the Bad Astronomy web site.

"The whole paradox was solved when we realised that our solar system must have settled into its Mercury-like position for part of the time it orbited the Oort cloud."

Dr Panchenko also added: "By creating a diplomatic solution to the pressure-cooker of the Oort cloud, the authors suggest that the comets which are now challenged by water ice may be able to move into the Oort cloud instead."

"This is a common scenario in the formation of planetary systems: Co-occurrence of one planet with a their icey satellites raises the chances for Earth's small Snowball Earth appearance- a planet orbiting a gas giant only to fall back into the gravity well of their parent gas giant."

Indeed, Earth's water reservoir seems to have been twice the size, or even more so, than the present-day world can sustain.
