2003 LA7, also written as 2003 LA7, is a resonant trans-Neptunian object that goes around the Sun once for every four times that Neptune goes around. This means it is in a 1:4 orbital resonance with Neptune. Another example of such object in this resonance is 2011 UP411.
2003 LA7 is in a 1:4 resonance with the planet Neptune.[1][2] For every one orbit that a it makes, Neptune orbits 4 times.
It is currently 43 AU from the Sun,[5] and will come to perihelion around 2041.[3]
Assuming a generic TNO albedo of 0.09, it is about 231 km in diameter.[4]
It has been observed 14 times over 4 oppositions.[3]
