Powerful Raycist

It's nearly impossible to reach the Sun because you inherit the Earth's inertia when you leave Earth. This means you're going at least as fast as the Earth's orbital velocity, which is 67,000 miles per hour (108,000 kilometers per hour), so you need to slow down. In the frictionless vacuum of space, it takes just as much energy to decelerate as it does to accelerate, so it takes the same amount of fuel to go from 67,000 MPH to zero as it does to go from zero to 67,000. NASA managed to get the Parker Solar Probe to the Sun by using using gravity from Venus to "tug" it in the direction opposite of Earth's orbit to slow it down. It took seven passes by Venus to accomplish this, orbiting the Sun 24 times. The whole process took seven years. It still didn't really reach the Sun, but now has a highly irregular orbit in which it passes close (in astronomical terms), and the Sun's gravity accelerates it so much that it gets flung back out to the orbital distance of Venus by the slingshot effect before returning. During those close passes, it becomes the fastest man-made object ever made, reaching speeds of 430,000 MPH (692,000 KPH).
