> If Earth was at one end of a yard-stick and the Sun on the other, Parker Solar Probe will make it to within four inches of the solar surface. 91cm and 10cm, to save anyone else doing the conversion. Also, it seems to understate the closeness: Closest approach is 6.1 million km, which is 1/24th of 1 astronomical unit, but four inches is 1/9th of a yard-stick. |
