Astronomers have detected what could possibly be a super earth in our solar system.

Astronomers have detected from the vicinity of the ALMA telescope an object of interest that is far away. It lies towards Alpha Centauri. It exists in the outer periphery of our solar system and could possibly be a super earth.

ALMA has the capacity of handling observations at short microwave lengths. These are given off by cold gas and dust. Objects on the edges of ths solar system would be giving off this light. The previous year, ALMA discovered such an object

This object was found to be in much clearer focus this year. It lies a few arc seconds off the Alpha Centauri axis. The Centauri system is four light years away, according to Forbes. From all appearances, it seems to be a red dwarf star.

However, it should have been clear in infrared light too. Such is not the case which makes the whole conundrum all the more intriguing. We can only make a guesstimate as to its size and distance.

There is a possibility that it is an extreme trans-Neptunian object and it lies 100 AU from the sun which is farther away than Sedna. And although it is as far away as Pluto, it is smaller than Pluto. 

Some say it is 300 AU away but is 1.5 times as big as the earth. This would make it the first instance of a super earth in our solar system. There has been talk of a few super earths in the outer limits of our solar system, so such a scenario is not so unbelievable.

The location is cause for greater precaution to be made during spouting hypotheses. Alpha Centauri is about 42 degrees away from the ecliptic. Most of the solar system is within a few degrees of the ecliptic. Even Sedna is only 12 degrees on an incline. The chances of a super earth are next to impossible. 

The last postulate is that it is a cool brown dwarf and it is 20,000 AU away. Such a phenomenon would be visible in infrared too. The only legitimate question is why it was never detected before.

The propinquity to Alpha Centauri would make such an object exist in plain view. More research via observational study needs to be done before a suitable answer can be seen to be forthcoming.
