(15836) 1995 DA2, also written as (15836) 1995 DA2, is a trans-Neptunian object. It was discovered on February 24, 1995, by David C. Jewitt and Jane X. Luu at the Mauna Kea Observatory, Hawaii.

Resonance[edit]

It is in a 3:4 resonance with the planet Neptune.[1][2] The Neptune 3:4 mean-motion resonance keeps the object more than 8 AU from Neptune over a 14,000-year period.[5][6]
