How the Parker Solar Probe will approach the Sun


Today’s Video of the Day from NASA explains why it requires 55 times more energy to go to the Sun than it takes to go to Mars.

The Parker Solar Probe only needs to drop 53,000 miles per hour of sideways motion to reach the Sun’s atmosphere,  but this will require seven years and seven gravity assists by Venus.

Ultimately, the probe will orbit closer to the Sun than ever before at a distance of just 3.83 million miles from the Sun’s surface.

The Parker Solar Probe will pick up speed as it goes, and is expected to break the record for the fastest-ever human-made object at 430,000 miles per hour during its final orbits.
