Today in the morning I wanted to a look at comet Neowise, but couldn’t find it in stellarium.
I’m rather new to this app, so this method is not perfect for sure.
Edit /usr/share/stellarium/data/ssystem.ini and append
[c2020f3%28neowise%29]
parent=Sun
orbit_Inclination=128.9373
coord_func=comet_orbit
orbit_Eccentricity=0.999191
orbit_ArgOfPericenter=37.2743
absolute_magnitude=7.5
name=C/2020 F3 (NEOWISE)
slope_parameter=5.2
lighting=true
tex_map=nomap.png
color=1.0, 1.0, 1.0
orbit_AscendingNode=61.0111
albedo=0.1
radius=5
orbit_PericenterDistance=0.294707
type=comet
orbit_TimeAtPericenter=2459034.1812962964
orbit_visualization_period = 2539576.6289147907
#orbit_good = 1000
dust_widthfactor = 1.5
dust_brightnessfactor = 1.5
dust_lengthfactor = 0.4
to it. Now you can search for “Neowise”.
