Why can't humans not travel to a planet in the solar system Kepler – 186F
VashaNatasha [74]
(Not related just helpful. can't not is a double negative. "I can't not leave'' means I can leave)
The biggest reason is probably we can even travel to Mars. Mars is only one planet away from us. the distance is to far for fuel and time. we would need to go much faster and a lot less fuel just to get to Mars.

Citrus2011 [14]

Answer:

The correct answer is B. From the study of the universe, we can say with certainty that the Sun becomes the vital factor of the solar system, where all the planets revolve around it and the Earth takes advantage of a privileged place.

Explanation:

Today, thanks to the advances in science and the studies that it has carried out regarding the universe and our galaxy in particular, we have a thorough knowledge of the solar system and its organization, which is what allows the optimal development of life in our planet.

Thus, the solar system, made up of the Sun, planets and other dwarf planets, satellites and minor celestial bodies, is an integrated system of space structures, the main component of which is the Sun. The Sun is a star, which through the force of gravity draws the planets into their orbit, causing them to rotate around it.

In turn, the Earth is the third planet closest to the Sun, after Mercury and Venus, with which it has enough heat to guarantee life, but without being so close that this heat prevents the development of life in the planet.
