Evidence of the first moon outside the solar system

There is strong evidence that a moon is flying around a giant gas planet 4,000 light-years away in the Swans.

If the object has been confirmed by the Hubble Space Telescope as a moon, this is the first moon to be found outside of our solar system.

So far, the strange thing about discovering distant space is that outside of our solar system with so many planets and most planets have their own moons, astronomers don't This can be found in other star systems.

In fact, finding a natural satellite of planets outside the Solar System is a difficult task for many reasons. The first is that the distance between us and the planets is too far, leading to a lack of reliable observation equipment. In addition, the lunar masses are often too small to be observable.

Kepler-1625b is a giant gas planet, its volume is 10 times larger than Jupiter.

However, the team of scientists from Columbia University in New York (USA) led by David Kipping tried to observe that 284 planets could have their own moon and from there separated a candidate with many degrees. The proof that there will be a moon exists is Kepler-1625b planet in the constellation Swans.

The giant moon

If the moon of Kepler-1625b exists and is proven to exist, it will be a completely different moon from what we know in the solar system.

Kepler-1625b is a giant gas planet, its volume is 10 times that of Jupiter, while its moon, if it exists, will have the same mass as Neptune. This means that the above moon will be about 17 times larger than the earth.

In some ways, these two objects can be classified into a double planetary system . In addition, it is difficult to know if such a large moon is "obedient" around the host planet.

In the case of Kepler-1625b being confirmed to have a moon flying around, the size of these two astronomical objects is difficult to create a stable moving trajectory.

Scientists have long argued that high-mass moons tend to fly out of the parent planet's orbit. This was confirmed when scientists observed 284 planets and did not encounter the possibility of a moon flying around them.

It is important to have or not have the moon around the mother planets, in the 1990s, astronomer Jacques Laskar of the French National Center for Scientific Research concluded that having a large moon is It is very important to stabilize the tilt of the Earth and thereby help the climate on our planet quite stable.

However, in more detailed simulations conducted by Jack Lissauer of NASA's Ames Research Center, it shows that without the Moon, the Earth will in fact only be shaken about 10 degrees, which is not enough to creating an environment that is too harsh for life.

In addition, astronomers also discovered that if the planet spins at high speed (one day under 10 hours), its axis is also very stable and therefore there is no need for a separate moon to be life.
