Anonymous users2024-02-06Why haven't humans been able to fly out of the solar system so far? Once you make a mistake, the probability of being rescued is zero.

Anonymous users2024-02-05Yes, human beings cannot fly in the solar system, but they are limited by the current technology, which is not enough to support such a long-distance flight.

Anonymous users2024-02-03Humans have not yet flown out of the solar system because of technological limitations. The current technology is far from enough for us to explore too far into space, let alone the solar system, and it will take us a long time to get to the planets that are far away.

Anonymous users2024-02-02The main reason is speed, and the speed bottleneck limit of the ship is the most important factor. Of course, there are many other important influencing factors. For example, survival security, ecological cycle, power energy, etc., are all very important constraints.
At present, the unmanned aerial vehicle Voyager 1, which has run the farthest distance of mankind, has flown for more than 40 years, and has only traveled more than 20 billion kilometers, only about 20 light hours. The gravitational range of the solar system is at least 1 light-year radius, and at this rate, it will take more than 10,000 years to fly out of the Great Sun System.
NASA announced that it will launch a solar probe on July 31 this year, which will reach a speed of 200 kilometers and seconds when approaching the sun, and it will take 1,500 years to fly out of the solar system at this speed, and it will take more than 6,300 years to reach the nearest star closest to us Proxima Centauri light-year, and it is not known whether it is a valid target for mankind.
In addition to the speed problem, the survival support, dormancy system, energy system, ecosystem and other technologies of the crew in interstellar travel are far from meeting the requirements of long-term space travel.
Therefore, it can only be a dream for humans to fly out of the solar system, and there is still a long way to go. The scientific community believes that it will take 3,000 to 5,000 years for mankind to reach the level of cosmic civilization, and by that time, it will be able to completely control all the energy and resources of the solar system, and it will have the ability to fly people out of the solar system and into distant interstellar space.

Anonymous users2024-02-01The reason why they can't fly out of the solar system is that humans are too slow.
According to the currently known edge of the solar system, it is the Kuiper belt, but many scientists believe that outside the Kuiper belt, there is an Oort nebula, and according to the range of the sun's gravity, the true range of the solar system is likely to be about 2 light years, according to the current speed of human beings, 1 light year takes 30,000 years, and the life span of human beings is only 100 years.
Therefore, there is no way for humans to really leave the Earth and the solar system, and it is likely that they have just flown over a few neighboring planets and have already died. It's not that humans don't want to fly out of the solar system, it's that humans simply can't do it, and the level of science and technology is not enough for humans to safely fly out of the earth and leave the solar system.
The composition of the solar system
The main lead-forming member of the solar system is the Sun, a G2 main-sequence star that occupies all known masses in the solar system, and the celestial bodies in the solar system move under the constraints of the sun's gravitational pull. Of the remaining mass, 99% is made up of the four large bodies of the solar system, known as the giant planets, and Jupiter and Saturn each account for more than 90% of them. The rest of the celestial bodies in the solar system (including the 4 terrestrial planets, dwarf planets, moons, asteroids, and comets) have a total mass less than that of the solar system.
The eight planets of the solar system can be divided into two groups according to their physical properties, one is terrestrial planets: small in size and high average density, slow in rotation, and few moons, including Mercury, Venus, Earth and Mars; The other type is Jupiter-like: large volume, small average density, fast rotation, more moons, Jupiter, Saturn, Uranus and Neptune, and the most special ones are Neptune and Saturn.
