Earth vs White dwarf
What are they, and what does the difference actually look like?
Two things. One honest scale.
Meet the pair
What these two things are
White dwarf
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.
12,000 kmDiameterThe mean diameter of Earth is about 1.06 times the diameter of White dwarf.

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

Why these numbers?
The visual compares mean diameter with diameter. The records below preserve each value’s basis and caveats.

- Comparing
- Mean diameter ↔ Diameter
- Relative size
- Earth is larger on this measurement by a factor of about 1.06. Earth's selected measurement is approximately 6.18% greater than White dwarf's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Earth is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
- White dwarf is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
