381 Myrrha is a C-type asteroid located in the asteroid belt, orbiting the Sun. It was discovered on January 10, 1894, by Auguste Charlois at the Nice Observatory. The minor planet is named after Myrrha and holds the provisional designations 1894 AS and A894 AC. In the sequence of numbered asteroids, it follows 380 Fiducia and is followed by 382 Dodona.
Physically, 381 Myrrha has a diameter of 127.639 kilometers and an albedo of 0.064. Its rotation period is 6.572 hours, and its absolute magnitude is 8.38. The asteroid is classified as an Outer Main-belt Asteroid.
Orbitally, the object has a semi-major axis of 3.234105578029831 astronomical units. Its orbital eccentricity is 0.08789247842360084, with a periapsis of 2.949852023293197 and an apoapsis of 3.518359132766465. The orbital inclination is 12.6099828639309 degrees, and the longitude of the ascending node is 124.7153787120321 degrees.

Pathfinder on Mars
2026-07-04
On July 4th, 1997, using its own array of fireworks, a parachute, and a cocoon of airbags, the Mars Pathfinder spacecraft bounced like a giant beach ball at least 15 times before it came to rest on the surface of Mars at 10:07 AM Pacific Daylight Time. After its then novel airbag-assisted landing sequence was completed, Pathfinder transmitted this color mosaic to mission operators on Earth. In the scene from another world, the Mars Sojourner robot rover is visible in the foreground, crouched on top of the unfolded Pathfinder. About the size of a large house cat, the six-wheeled, solar-powered Sojourner became the first successful Martian rover. Surrounding Pathfinder are deflated airbags and the rock-strewn terrain of the Ares Vallis floodplain. In the distance Martian hills appear against a dusty brownish sky. The Pathfinder lander was subsequently renamed the Carl Sagan Memorial Station.

Encyclopedic overview
381 Myrrha is a main-belt asteroid that was discovered by the French astronomer Auguste Charlois on January 10, 1894, in Nice. It has been classified as a C-type asteroid and is most likely composed of carbonaceous material.
Photometric observations of this asteroid at the Oakley Observatory in Terre Haute, Indiana during 2006 gave a light curve with a period of 6.572 ± 0.002 hours and a brightness variation of 0.34 ± 0.05 in magnitude.
