169/NEAT is a periodic comet in the Solar System. It is the parent body of the alpha Capricornids meteor shower in Late July. 169/NEAT may be related to comet P/2003 T12 (SOHO).[3] It comes to perihelion (closest approach to the Sun) on 9 July 2022.[1] On 13 July 2022 passed 0.1395 AU (20.87 million km) from Venus.[4] On 11 August 2026 it will pass 0.1672 AU (25.01 million km) from Earth and then come to perihelion on 21 September 2026.
169P is a low activity comet roughly a few kilometers in diameter.[5] 169P and the smaller body P/2003 T12 likely fragmented from a parent body roughly 2900 years ago.[5]
