Good to Know About Hands to Astronomical Units Conversion

A horse standing at 16 hands is about 1.63 meters tall at the withers. The Sun is about 92 billion such horses away. Equestrian measurement was not designed for interplanetary comparison.

Hands to Astronomical Units: What You Need to Know

The Earth-Sun distance (1 AU) is about 1.473 x 1012 hands (about 1.5 trillion). The tallest horse ever recorded (21.25 hands) was 1.443 x 10-11 AU tall. Even stacking every horse on Earth would not approach 1 AU.

What is a Hand? hh

Exactly 4 inches (10.16 cm). The standard unit for measuring the height of horses, measured from the ground to the withers.

Hands to Astronomical Units FAQ

  • One hand equals approximately 6.791 x 10-13 AU.

  • One AU contains approximately 1.473 x 1012 hands (about 1.5 trillion).

  • No. Horses and planetary orbits occupy different measurement universes.

Non-Frequently Asked Questions About Hands to Astronomical Units

Questions nobody should ask - but someone did.

  • The Sun is 1 AU = about 1.473 x 1012 hands away. At 16 hands per horse, you need about 92 billion horses stacked. Earth has about 60 million horses. You would need about 1,533 Earths' worth of horses. Horse breeding needs to scale up considerably.

  • No. A 16-hand horse (1.63 m) seen from 1 AU (149.6 million km) would subtend an angle of about 10-11 radians. The Hubble Space Telescope resolves about 2.4 x 10-7 radians. The horse is about 24,000 times too small for Hubble. Horses do not photograph well from the Sun.

  • A horse gallops at about 60 km/h. The Sun is 149.6 million km away. At constant gallop: 149,600,000 / 60 = 2,493,333 hours = 284.7 years. The horse would need about 14 generations of relay riders. Space travel by horse is impractical even with wings.
