A little perspective
Venus vs White dwarf: diameter comparison
The mean diameter of Venus is about 1.01 times the diameter of a white dwarf.
Venus is a rocky planet orbiting the Sun, covered by thick clouds of carbon dioxide and sulphuric acid.
A white dwarf is the dense, hot remnant core left behind after a star like the Sun has exhausted its nuclear fuel and shed its outer layers.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.

Venus
Mean diameter: 12,100 km; approximate.
Mean-radius spherical model for Venus; actual shape is not perfectly spherical.
NASA JPL — planetary physical parameters
The marked mean diameter is calibrated. Unmeasured illustration details are representative.
White dwarf
Diameter: 12,000 km; representative.
A chosen 12,000 km, 0.6 solar-mass white dwarf. These remnants have roughly planetary dimensions but stellar masses.
The marked diameter is calibrated. Unmeasured illustration details are representative.
