Shooting at the sun in outer space, the bullet will eventually reach the sun, or keep moving

As we all know, if you shoot a bullet into the air with a gun, it will be powerful enough to fly as far as two kilometers; if you shoot a bullet into the water with a gun, it will be weak enough to fly as far as two meters.

But what happens if we shoot at the sun in outer space? Will the bullets stop? Or will they keep moving? Or will it finally reach the sun?

This problem is too complicated. The object will always keep a straight line motion without external force.

But in a vacuum, unless you don’t encounter a meteorite, and the angle is accurate enough not to be attracted by other planets, it’s possible.

However, vacuum is not the same as the ideal state of absolute freedom from external force. In vacuum, there should also be various elements and ions floating. The volume of these materials will decrease with the increase of volume, but it will also affect the speed. So in a long enough time, the speed and direction of the bullet should change.

In short, it can be understood as follows:

Shooting at the sun with a gun in outer space, the bullet will not hit the sun.

Because the sun and the earth as well as all celestial bodies in space are in motion, the position between the earth and the sun is constantly changing.

It’s like taking a sniper gun to shoot a cheetah running at a high speed in the distance, aiming and shooting directly. When the bullet reaches that distance, the cheetah has already left the original aiming point.

If you want to hit the running cheetah, you need to calculate the distance of the target and the moving speed of the target in advance, aim at the front of the running direction of the target and shoot a certain distance to hit it.

In addition, there are various factors that affect the trajectory of the bullet, such as the gravity of the earth, the moon and the planets in the solar system, which will lead to the trajectory change.

So shooting at the sun in outer space, the bullet will not reach the sun in the end. Otherwise, human beings would have nothing to do every day to send micro detectors to the sun.
