evidence that the subject meets any of the specific criteria for astronomical objects;

or multiple published secondary sources that:

provide significant coverage: discuss the object in detail, not just brief mentions or database entries;
are reliable: from reputable scientific outlets with editorial oversight.

Please add references that meet these criteria. If none exist, the subject is not yet suitable for Wikipedia.

Atla Regio is a region on the surface of Venus,^[1] located at the equator^[2]^[3] in the coordinates 9.2°N 200.1°E.^[4], and measuring about 3,200 kilometres (2,000 miles) in diameter^[1]

Its name derives after the Norse giantess, the mother of Heimdall, which was accepted by the International Astronomical Union in the year 1982.^[1] On Venus, regions are named after giantesses and Titanesses^[4]

Geology

Atla regio is a large rise that sits above a rising section of Venus's mantle. It has several giant shield volcanos which inludes Maat Mons, Ozza Mons, and Sapas Mons.^[5]^[2] Atla Regio is modified by tectonism, which acts as major centers for converging rifts^[3]
