An artificial space body began to move from the Earth with the third cosmic speed. How soon will it reach the stars?

The trajectory of this artificial body is a parabola. A body moving in a parabola at large distances from the Sun will have a velocity close to zero. The flight even to the nearest stars will take an extremely long time – millions or billions of years. Much more preferable is the hyperbolic orbit, in which the body, even at a very far distance from the Sun, will have a velocity different from zero.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
