What is "schaeberle"

Schaeberle may refer to:

• John Martin Schaeberle (1853–1924), a German-American astronomer; and things named for him:
  • Schaeberle (lunar crater)
  • Schaeberle (Martian crater)

Schaeberle is an impact crater on the far side of the Moon. It lies to the northeast of the much larger walled plain Milne. Due north of Schaeberle is the relatively fresh crater Izsak, and an equal distance to the east-northeast lies Zhiritskiy.

This crater has a worn and eroded outer rim. There is a small crater attached to the outer rim along the northwest, and an irregular section at the southern end. What marks this crater as relatively unusual for a far side formation, however, is the interior floor. It has the relatively lower albedo that is characteristic of resurfacing by flows of basaltic lava, although it is not nearly as dark as the floor of Tsiolkovskiy. The floor is marked only by a few tiny craterlets.

Schaeberle Crater is a crater in the Iapygia quadrangle of Mars, located at 24.7° S and 309.9° W. It is 160 km in diameter and was named after John Martin Schaeberle, an American astronomer (1853–1924). Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak. The peak is caused by a rebound of the crater floor following the impact. If one measures the diameter of a crater, the original depth can be estimated with various ratios. Sometimes craters expose layers that were buried. Rocks from deep underground are tossed onto the surface. Hence, craters can show us what lies deep under the surface.
