2019da

2019 DA is the provisional designation given to a small near-Earth object discovered in 2019. Provisional designations are issued by the Minor Planet Center to newly found objects and indicate the year of discovery (2019), followed by a two-letter code that encodes the half-month of discovery and the object’s sequence within that period. As such, 2019 DA remains not yet numbered or named, pending a well-determined orbit.

The object was detected by a ground-based survey in 2019 and has since been tracked by multiple observatories to refine its orbital path. Details such as orbital elements and size estimates are provided by the MPC and asteroid surveys; for many objects of this size, the diameter is uncertain and depends on assumptions about reflectivity.

2019 DA is classified as a near-Earth object, meaning its orbit brings it into proximity with Earth's vicinity. Objects like this are monitored to assess any potential close approaches and to update risk assessments as more astrometric data are collected. The designation will remain in use until a stable orbit is confirmed and a permanent number or name is assigned.

This entry reflects how provisional designations function within the broader context of asteroid tracking and the ongoing effort to catalog small bodies in the inner solar system.
