  Why does it take 8 years to get to Mercury?! #shorts

  Basically, sending stuff to Jupiter is like putting up hill in golf, and sending stuff to Mercury is like putting down hill in golf. If you’re not careful, the ball will pick up too much speed and fly past the hole. So when you send something to Mercury, you need a way to slow down the spacecraft, so that it doesn’t just fly past Mercury. You could just use fuel to slow down but that would require a lot of fuel, whereas planet fly-bys allow you to change the relative speed and direction of a spacecraft for free. So passing behind a planet in the direction of its orbit pulls the spacecraft forward, stealing a tiny bit of the planet's orbital energy to increase the spacecraft’s speed. Whereas, passing in front of a planet means the spacecraft is working against the planet's movement, and so it instead transfers a tiny bit of energy to the planet’s orbit which reduces the spacecraft’s speed. So the most efficient way to get to Mercury is through many planet fly-bys. After Bepi Colombo launched, it slowed down with one fly-by of Earth, two of Venus and six of Mercury. So the Bepi Colombo mission is a real feat of both engineering and orbital dynamics to make it possible for us to orbit Mercury so close. And it’s all in the name of science.
