To help compare orders of magnitude of different times this page lists times between 10¹⁷ seconds and 10¹⁸ seconds (3200 million years and 32 000 million years) See also times of other orders of magnitude.

• Shorter times
• 3,500 million years -- age of oldest life (bacteria)
• 3,700 to 3,900 million years -- age of the Mare Imbrium
• 4,468 million years -- half-life of uranium-238
• 4,500 million years -- age of Earth (see: Precambrian)
• 10,000 million years -- expected Main sequence lifetime of a G2 dwarf star (like the Sun)
• 13,700 ± 200 million years -- estimated age of the Universe according to Big Bang theory
• Longer times
