# Venus

*In the Solar System*

Nearly the Earth's twin in size and mass, and nothing like it anywhere else. A carbon-dioxide atmosphere ninety times the pressure of ours holds the surface at about 465 °C - hotter than Mercury's, and the same all over, day side and night - under permanent cloud of sulphuric acid. It turns backwards, and so slowly that its day is longer than its year.

Distances and speed are computed from JPL Horizons trajectories and are true of 2026-09-05, changing at the rate given beside each. The interpolation itself is good to a few kilometres; what ages these figures is the date, not the arithmetic.
