According to several sources, Coronavirus is a helical virus, i.e. it should have a helical capsid. Although most sources did not labelled or pointed any kind of capsid. It was mysterious to watch diagrams of spherical envelops with no underneath capsids.

No mention of capsid.
Initially I guessed the proteins around the RNA fibre formed the capsid, not labelled otherwise. Alternatively I was speculating whether coronavirus is lacking the capsid.
It makes me think of whether the capsid is like a hollow spherical or polygonal thing spirally wrapped.
Now my questions are .
What is the actual/ realistic shape of coronavirus capsid?
Does it really contain a capsid?
(Just speculating) Is it SARS-CoV2 lacking a capsid, and thus special exception from g eneral description of coronavirus?
