~1.5 million km
The James Webb Space Telescope travels around the Sun near the Sun-Earth L2 region, about 1.5 million kilometers from Earth. It does not circle Earth the way Hubble does.
243 days
Venus takes about 243 Earth days to rotate relative to the stars, longer than its 225-day year. Its solar day, measured from one sunrise to the next, is shorter: about 117 Earth days.
1B tons
A teaspoon-sized volume at neutron-star densities can have a mass of roughly a billion tons. This is a density comparison, not a suggestion that stable spoonfuls could be brought to Earth.
