Earth, Venus, Mercury... and the Parker Probe. It keeps flying near Venus and getting pushed closer to the Sun. In September it came within 25 million kilometers of the Sun. In January it will get closer: 19 million km. That's HOT! But that's just the start... (1/n)pic.twitter.com/tt1CxjBV3e

By the end of 2024 it will come within 7 million kilometers of the Sun. That's 1/9 as far as Mercury is from the Sun, so the Sun will look 81 times brighter than on Mercury. It's just 10 solar radii from the Sun's center! It'll be moving at 0.064% the speed of light. (2/n)pic.twitter.com/5icLvr0ISp

On Earth, the Sun is half a degree across. To the Parker probe at its closest approach, it will look 28 times bigger across. The probe's heat shield will reach 1,400° Celsius. But amazingly, the spacecraft's payload will stay near room temperature! (3/n)pic.twitter.com/RqxLpl237W
