Question about slightly older Pluto images. Pluto is noted in these glass plates from Tombaugh's discovery in 1930. What is (are) the other item(s) highlighted in red?

Question about slightly older Pluto images. Pluto is noted in these glass plates from Tombaugh's discovery in 1930. What is (are) the other item(s) highlighted in red? We can rule out another TNO, given it is not moving in the same general retrograde direction as Pluto. MBAs and NEOs can also be ruled out for similar reasons. Knowing how thorough Tombaugh was with his survey, he wouldn't have overlooked something of that magnitude. The non-symmetrical appearance in both images suggests they were specks of dirt on the plates when they were eventually scanned. |
