NASA has so far discovered 5 exoplanets (planets outside the Solar System), scoring what exactly they are. These exoplanets have been uncovered by various telescopes, but it is not known the type they belong to (Gas Giant, Neptune-like, Super-Earth, etc.).

Can hide these exoplanets, unseen worlds? Well, the answer is yes. It doesn't really matter if we classify that planet in one way or another, it matters that there is also in this way and an undiscovered world can exist there. The problem is, these exoplanets have chances to not exist.

NASA discovered them in some way through different methods. But it is not known exactly that the 5 exoplanets discovered by NASA are really exoplanets or they can be something else or they can be nothing.

Of the 5 exoplanets that NASA does not know what they are, 3 of them belong to the KIC 10001893 system, their name being KIC 10001893 b, KIC 10001893 c, KIC 10001893 d.

The other two exoplanets, named LkCa 15 b, LkCa 15 c were discovered by a method by which we theoretically know there is something there. We mean, the Direct Imaging method.

However, the LkCa 15 b exoplanet was denied its existence in 2019 after several high-resolution images became available. The exoplanet LkCa 15 c was also rejected, with scientists arguing that the new images became much clearer, proving that there was nothing there.

Thus, out of the 5 exoplanets that do not yet know what they are, discovered by NASA, only 3 of them have at least the possibility to exist. These three may be new worlds, of which we probably know nothing by now.

But, can they sustain life? The answer to this question is: most likely not. The star around which the 3 exoplanets revolve is type B, and the three exoplanets take them between 0.2-0.8 days to make an orbit around their star.

Also, according to NASA, the habitable area is extremely far from where the exoplanets are now. Our Sun has a temperature of approx. 5700-5800 K, well, this star has 27000-28000 K on the surface, and the exoplanets are relatively close to the star.

So the possibility of life there, it's almost impossible. But we hope NASA will discover exactly what these exoplanets are. There are various rumors that the 3 exoplanets changes their shape, which has not yet been confirmed.

We wait to see what type of exoplanets they are or if there is any type for them, except the "unknow" type.
