Earth
Mean-radius spherical model for Earth; actual shape is not perfectly spherical.
Defined examples — our methodology
The marked age is calibrated. Unmeasured illustration details are representative.

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

Mean-radius spherical model for Earth; actual shape is not perfectly spherical.
- Comparing
- Time ↔ Age
- Relative size
- Earth is larger on this measurement by a factor of about 4.54. Earth's selected measurement is approximately 354% greater than 1 billion years's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Earth is labelled rounded geological anchor; treat the displayed value as a comparison anchor rather than false precision.
