It promises to be a remarkable moment in the history of space exploration.
A year from now, on 24 December, Nasa’s Parker Solar Probe will race past the Sun at the astonishing speed of 195 km/s, or 435,000 mph.
No human-made object will have moved so fast nor, indeed, got so close to our star - just 6.1 million km, or 3.8 million miles from the Sun’s “surface”.
“We are basically almost landing on a star,” said Parker project scientist Dr Nour Raouafi.
“This will be a monumental achievement for all humanity. This is equivalent to the Moon landing of 1969,” the Johns Hopkins University Applied Physics Laboratory scientist told BBC News.
I am not a smart man, but 6.1 million km seems like really far away from something.
The sun is 1.4 million kilometers in diameter. 6 meter from a 1 meter diameter sphere is relatively close.
Also the sun’s corona stretches out about 8 million kilometers from its surface, so for this probe its like its moving inside the earths atmosphere.
So… pretty dang close.
Tfw the suns atmosphere is significantly wider than our planet, several times over
For perspective because I didn’t know either:
Mercury from sun: 49.93 million km
Earth from sun: 147.11 million km
Still sounds sensationalist to say it’s like landing on the sun, but close on the solar system scale.
