Comet Palomar Time Lapse

How many UFOs have you seen in your career?

Well for one thing, it's almost opposite the sun in our sky. The tail would point away from the sun, so even if it had a long tail it would be dramatically foreshortened. Not all comets develop significant visible tails though, and the distance from the sun matters a great deal as to when or if the tail will develop. This comet will not get closer than about 2 AU from the sun, so it would not be uncommon for it to never develop a visible tail.
"It has been stated that comets begin to produce tails at heliocentric distances varying from 1.5 a.u. downward.1
In 1953, G.
Merton,3
in reporting on observations of P/Comas Solá, 1951 h,
commented on the observation by L. Kresák of a tail 15' long
on November 26, 1952 : . . remarkable, considering that the
heliocentric distance was 1.9 a.u."
