If this so-called 'Exomoon' really exists, it could potentially be similar to Neptune in terms of weight and size, according to the astronomers who claim to have found it. The planet circled by this exomoon could be as big as Jupiter while having 10 times its weight.

Up until this point experts were not able to find predictions of a moon similar to Neptune in terms of size. In spite of this fact, astronomy expert Dr Kipping believes that this does not mean it's not possible.

How was it first seen?

It was first observed with the Kepler Telescope owned by Nasa and experts seem interested in the potential discovery, so they many astronomers are planning to find out more about it in October, when the Hubble hi-tech telescope is going to be used.

What about the so-called exoplanets?

What's interesting is that there are many distant exoplanets discovered by scientists up until now, as many as 3,000. There is also a quest for finding exomoons, meaning the celestial objects which orbit around those exoplanets. They seem to be even more difficult to detect, even with the hi-tech spatial equipment used by astronomers.

How interested are astonomers in these exomoons?

There are astronomers such as Dr David Kipping from the Columbia University in NY who are fascinated by this type of Celestial Objects which have not yet been confirmed to exist. Some of them even say they have spent a great part of their lives trying to discover these exomoons.

What if the first exomoon was not discovered?

It's possible that astronomers have not yet discovered the first exomoon, as expert Dr David Kipping stated. He believes there are chances that what was thought to be the first exomoon would actually be another kind of celestial object. At the moment astronomers think it is similar to a moon, but it is not yet confirmed whether it really is a moon.

The Kepler spatial equipment did receive the signal that made astronomers think their search for the exomoon could have been successful. However, they were not able to be sure of their discovery because the signal was not noticed enough times for them to be sure of the great news.

Even though experts have not yet been able to confirm the existence of what the call an exomoon, the chance of it being discovered and the possibility of finding other types of interesting celestial objects with today's modern equipment is still something that makes a lot of people fascinated.
