Asteroid belt
Ceres is the only recognized dwarf planet in the main asteroid belt between Mars and Jupiter. Its nearly round shape distinguishes it from the many smaller, irregular bodies sharing that region.
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.
