The temperature and radiation it has to endure is impressive, but I'm more blown away by good old fashioned gravity assists to yeet the probe and not have it fall into a fiery well of gravity.
- ethbr1 2y ago192 km/s is pretty insane. That's 0.06% of light speed? And a bit over 10x what the Voyagers are traveling at?
- holoduke 2y agoWonder what the time dilation would be. Must be in seconds with that soeed.
- belter 2y agoBy my rough calculations about 18 milliseconds of time dilation per day assuming 690,000 km/h - 430,000 mph.
- divbzero 2y ago18 milliseconds per day is roughly 6.5 seconds per year: same order of magnitude as itishappy’s estimate elsewhere in this thread.
- itishappy 2y ago1 / sqrt(1 - v^2 / c^2) 1 / sqrt(1 - v^2) (when v is in units of c) 1 / sqrt(1 - 0.0006^2) 100.000018% or about 5 seconds per year (I may have this reversed, but it doesn't really affect the numbers at this speed, just the sign.)
- stouset 2y agoHitting the sun is actually surprisingly hard. It’s harder than leaving the solar system. Earth orbits at around 30km/s and you need 42km/s (+12km/s) to escape orbit.
