Comparison of size of the Kuiper belt (large faint torus) with the star VY Canis Majoris (within Saturn's orbit), Betelgeuse (inside Jupiter's orbit) and R Doradus (small central red sphere) together with the orbits of Neptune and Uranus, to scale. The yellow ellipses represent the orbits of each planet and the dwarf planet Pluto.

To help compare different distances, this page lists lengths starting at 10¹² m (1 Tm or 1,000 million km or 6.7 astronomical units).

Distances shorter than 10¹² m

• 1.079 Tm — 7.2 AU — One light-hour
• 1.4 Tm — 9.5 AU — Distance between Saturn and the Sun
• 2.0 Tm — 13.4 AU — Diameter of one of the largest known stars, KY Cygni
• 2.5 Tm — 16.7 AU — estimated diameter of VY Canis Majoris (up to 2.9 Tm or 19.5 AU)
• 2.9 Tm — 19.4 AU — Distance between Uranus and the Sun
• 4.4 Tm — 29.4 AU — Perihelion distance of Pluto
• 4.5 Tm — 30.1 AU — Distance between Neptune and the Sun
• 4.5 Tm — 30.1 AU — Inner radius of the Kuiper belt
• 5.7 Tm — 38.1 AU — Perihelion distance of Eris
• 7.3 Tm — 48.8 AU — Aphelion distance of Pluto
• 7.5 Tm — 50.1 AU — Outer radius of the Kuiper Belt, inner boundary of the Oort Cloud
