1 petametre

To help compare different distances this page lists lengths starting at 10¹⁵ m (1 Pm or 1,000,000 million km or 6,700 astronomical units or 0.11 light years).

Distances shorter than 10¹⁵ m

• 7.5×10¹⁵ m — 50,000 AU — Possible outer boundary of Oort cloud (other estimates are 75,000 to 125,000 or even 189,000 AU (1.6, 2, and 3 light years, respectively))
• 7.7×10¹⁵ m — 52,000 AU — Aphelion distance of the Great Daylight Comet of 1910
• 9.46×10¹⁵ m — 63,000 AU — One light year, the distance travelled by light in one year

Distances longer than 10¹⁶ m
