39041

39041 is an asteroid located in the outer region of the main asteroid belt between the orbits of Mars and Jupiter. It was discovered on October 24, 1981, by American astronomer Edward L. G. Bowell at the Anderson Mesa Station of the Lowell Observatory in Arizona. The asteroid was named after the astronomer’s wife, Marjorie Bowell, with the "41" appended to her name to comply with the International Astronomical Union’s naming conventions for minor planets.

39041 Marjorie is classified as a carbonaceous asteroid, suggesting it is composed of primitive materials similar to those found in carbonaceous chondrite meteorites. These types of asteroids are believed to contain organic compounds and are of significant interest to scientists studying the early solar system and the origins of life. Its composition indicates it has likely remained largely unchanged since its formation around 4.6 billion years ago.

The asteroid has an estimated diameter of approximately 10 kilometers (6.2 miles) and follows a relatively stable orbit with a semi-major axis of about 3.16 astronomical units (AU) from the Sun. Its orbital period is roughly 5.6 years, and it has a low inclination of around 1.5 degrees relative to the ecliptic plane. Observations suggest it has a relatively slow rotation period, taking about 10 hours to complete one full spin.

While 39041 Marjorie is not considered a near-Earth object, it remains an important subject of study for astronomers interested in the composition and dynamics of the outer asteroid belt. Its classification as a carbonaceous asteroid provides valuable insights into the conditions of the early solar system and the potential delivery of volatile and organic materials to terrestrial planets.
