Birger Johansson refers to the “planetoid 1996 TL, beyond Neptune”
(Letters, 14 February, p 53).
1996 TL is a perfectly routine outer-mainbelt minor planet.
Your correspondent was probably referring to the object 1996 TL66, which is
beyond Neptune, but is only one of some 60 such objects that are known.
An up-to-date listing of these objects can be found on our website at:
