Parker will make 24 close approaches to the sun over the next seven years, ultimately coming within just 3.8 million miles (6 million kilometers).

Launched in August, Parker is on track to set another record late Monday night. It will surpass Helios-2's speed record of 153,454 miles per hour (247,000 kilometers per hour), relative to the sun.
