How do long range space probes like Voyager 1 anticipate traveling through space for hundreds or thousands of years without hitting something, getting pulled into something’s gravity and crashing, etc?
In: Planetary Science
Space is so big and so empty that the smallest distances between two objects are measured in the hundreds of thousands of miles.
That’s the distance for asteroids in an asteroid belt.
The distance between planets is millions and millions of miles and the space between solar systems is hell I’m not even sure how many zeros that would be because we made a whole new unit just to express that distance.
The next closest solar system is approximately 25 trillion miles away.
25,000,000,000,000.
Think about that. It takes 1000 millions to make 1 billion and it takes 1,000 billion to make 1 trillion so 25 trillion would be 2,500 billion to put it in a different way.
