C/2018 N2 (ASASSN) & 260P/McNaught @ 7-September-2019 10:46 UT

On September 7, 2019 the comets C/2018 N2 (ASASSN) and 260P/McNaught crossed in the sky on this field full of small galaxies in Aries constellation. Its minimal angular separation was only 10 arcminutes, although only due our perspective from Earth, as both comets were far away from each other; at bottom comet 260P/McNaught to 0.6 A.U. from us and at upper comet C/2018 N2 (ASASSN) to 2.6 A.U., two times the distance from Earth to Sun separates them.
