Why can Voyager 1, which arrived at the edge of the solar system, avoid hitting other celestial bodies in flight

At the moment when people step out of the universe, they are deeply fascinated by the mystery and beauty of the universe. Man has only stepped out of the earth, but not out of the solar system.

In the eyes of scientists, the edge of the solar system is a very mysterious area. Because it is too far away, the sun can no longer shine. Therefore, it is difficult for scientists’ telescopes on the earth to observe some conditions of the edge of the solar system. Only by sending space probes one after another and arriving there can they really begin to understand this mysterious area.

Voyager 1

It is a space probe developed by NASA, weighing 815kg, launched on September 5, 1977. It has visited Jupiter and Saturn. It is the first space probe to provide detailed and clear pictures of Jupiter, Saturn and its satellites for human beings. At the same time, it is also the farthest man-made spacecraft from the earth.

Voyager 1, who has been in space for 43 years, why didn’t it hit other celestial bodies?

Voyager 1 has been flying for 43 years since it was launched. After the gravitational acceleration of Jupiter and Saturn, it has exceeded the speed of the third universe, so it can fly outside the solar system.

After nearly half a century of flight, Voyager 1 has never collided with other celestial bodies. Not only that, Voyager 1 is still in a very good state. It can not only send back signals to the earth, but also receive various instructions from earth scientists.

Voyager 1’s first target is Jupiter. In its flight to Jupiter, it needs to pass through the asteroid belt between the orbits of Mars and Jupiter. It is estimated that there are at least 500000 asteroids in the asteroid belt, the largest of which is Ceres with a diameter of 950 km. There are at least 200 asteroids with a diameter of more than 100 km and at least 700000 asteroids with a diameter of more than 1 km.

Although there are a large number of objects in the asteroid belt, they are very scattered, so it is difficult to collide. In such a vast space, the average distance of each celestial body in the asteroid belt can reach 1 million kilometers, which is 78 times the radius of the earth.

It can be seen that the asteroid belt is actually very open. In addition, the objects in the asteroid belt are very small and the gravitational effect is very weak, so it is almost impossible for Voyager 1 to collide with other objects during its flight. The same is true for other detectors.

After crossing the asteroid belt, the traveler soon arrived at Jupiter. Scientists initially designed the path for Voyager 1 to fly 350000 kilometers above Jupiter. After leaving Jupiter, Voyager 1 accelerated to Saturn, and it also flew over Saturn.

However, in order to observe Titan, Voyager 1’s flight trajectory changed. Voyager 1 flew out of the ecliptic, so it did not continue to visit Saturn’s neighbors Uranus and Neptune.

Because the Kuiper belt is sometimes very open, even if Voyager 1 passes, there will be no asteroid collision.

Xiaobian believes that all our aircraft are set up and planned by scientists in advance, and the universe is so vast that the possibility of their collision with other celestial bodies is almost zero. It is now, and it will be in the future.
