Not to put too fine of a point on it, but it's due to it not being part 
of the source packages of the upstream EL.

It was probably removed due to the upstream EL's focus on GNOME and 
GNOME applications; kstars is KDE, and KDE is a second-class citizen in 
the upstream and has been for quite a while.  So trimming down KDE so 
that more GNOME stuff could be included would fit upstream's model.

If you want the same interface and version as you are used to in EL5, 
please see the Trinity Desktop repository for packages: 
https://wiki.trinitydesktop.org/RedHatInstall

The trinity-kstars package and its dependencies from that repo install 
well on EL7.
