When will we visit the Second Earth?

With today's science and technology, the answer is . 26 million years.

How long will it take for us to visit the Second Earth?

A few hours ago, NASA commissioned the Kepler space telescope to discover a new planet that has properties very similar to our Earth and named it Kepler-452 . The planet belongs to a 'Solar System' in the constellation Cygnus of the Milky Wat galaxy, 1400 light years from Earth.

Immediately, scientific lovers in the world have welcomed this news in a very excited way because this is a breakthrough discovery in the mission of finding life outside the universe. Even many people began to think about launching spacecraft to the planet to explore. But is it really that simple?

Notice that the " light year " is the distance, not the time.

The fastest spacecraft today - New Horizons.

The current fastest spacecraft of the human race is New Horizons, which plays an important role in NASA's recent Pluto mission. New Horizon's speed reached 15.73 km / s which is equivalent to the number of 496,061,280 km / year.

With the distance between the two Earths being 1400 light years and a light year equivalent to a distance of 9,460,730,472,580.8 km, we can do a calculation to find out how long it takes people to reaching this planet: (9,460,730,472,580,8 / 496,061,280) x 1,400 = 26,700,375,9326 years.

At this point we must definitely be alert when the period of more than 26 million years is an unimaginable number for any dream. Hopefully in the future the speed of the spacecraft will be improved so that one day, setting foot on this 2nd Earth is no longer a fantasy.
