Hypothesis of the fate of the Earth if the universe exists 2 Sun.

If the universe exists 2 suns, what will be the fate of the Earth? This is a hypothetical question given by many scientists.

Most stars like the Sun are binary stars and they spin around each other. Our sun can also have a twin "brother".

In fact, astronomers have observed two exoplanets moving around a binary star system like the fictional Tatooine planet in Star Wars by Luke Skywalker. They also discovered many planets in galaxies that have up to 2 and even more than 2 Suns, and scientists also question how it would be if the Earth had two Suns.

Kepler-16b is the first planet discovered, astronomers say that the temperature on this planet is extremely low because it is influenced by two dim stars (only as small as 60% and 20% compared to the face). Heaven of Earth). If the Earth is in such a situation, all the water on Earth will freeze and the temperature will drop to minus 73 degrees C.

If the universe has 2 Suns then Earth will have many changes.

Leading the San Diego State University team, William Welsh said, before that, scientists were very skeptical about the viability of "double orbit". But since these three planets have been discovered, we know the possibility of having at least several million such planets in the Milky Way.

Like the Kepler-16b case, we will have 2 dusk (or 2 dawn). The number of real Japanese phenomena also increases when a Sun moves forward.

Therefore, the Earth's axes will be affected by two suns at the same time, so the climate will often change and consequently the seasons will change very quickly.

Jerome Orosz of San Diego State University said: " The planets around 2 Suns can have a crazy climate that none of them can be. Every year here four seasons will go through many cycles, with with a terrible temperature difference ".

In addition, Earth's orbit will change a lot and the rotation time will be longer, then the system of hours and seasons as well as the number of days, months, years . will be re-divided according to another system (or also maybe unit time will change, otherwise it will be very inconvenient).

The existence of two solar at the same time will increase the number of lighting days. If this happens, people will only sleep a few hours.

It can be seen that if the Earth has 2 Suns, human beings and many organisms will be difficult to adapt to this living condition because of the constant fluctuation in temperature, time, climate .

According to astronomers, if there are two suns in the system, the Earth can be cooked, drifted indefinitely in space or frequently undergo a 5-hour solar eclipse.

In binary star systems, the fate of the Earth depends on many factors from the masses of the two stars until the Earth's position will probably cause the Earth to be unstable. It is very likely that the Sun will pull planets, including the Earth towards it.

At this time the Earth will be baked before it disappears. On the other hand, if no stars have enough gravitational force, Earth will drift into space and become a wandering planet.
