hi! you may be interested in this pile of posts which all talk about the names/naming of the planets (including non-Roman-god-derived) and the relationships between the planets and the gods they were named after:

• Why are the planets of our solar system named after the Roman Pantheon or vice versa?

• Why did planets get named after Roman Gods and not Egyptian, Greek or Norse? and this addendum for more examples of planets not named after Roman gods Can you tell me about Non-Greek names of planets and their discoveries in India, China etc?

• Was it coincidence that Jupiter, the largest planet in the solar system, was named by the ancient Romans/Greeks after the king/father of the gods? Or did they somehow have an idea of its true size? - includes links to several more re the relationship between planets & gods

• more examples of planet names What planets were known to non-Western cultures before modern telescopes, and what names did they give them?

They are closely identified (but this doesn't mean that the god is only the planet).

I don't have time for an exhaustive reply but here is a place I remember well:

For example, when at the end of the second book of the Aeneid the morning star (Lucifer) appears guiding Aeneas to finally leave the destroyed Troy, then it is very transparently his mother Venus guiding his way (Venus is stella matutina [=lucifer] and guides as stella maris the way for seafarers, nowadays these are epithets of the Virgin Mary; Venus rises as the morning star in the East and sets as the evening star in the West guiding Aeneas' voyage from Troy to the "evening-lands" of Italy).

Iamque iugis summae surgebat Lucifer Idae
ducebatque diem, Danaique obsessa tenebant
limina portarum, nec spes opis ulla dabatur;
cessi, et sublato montes genitore petivi.

Now above the crest
of loftiest Ida rose the morning-star,
chief in the front of day. The Greeks held fast
the captive gates of Troy. No help or hope
was ours any more. Then, yielding all,
and lifting once again my aged sire,
for refuge to the distant hills I fled.

(translation by Theodore C. Williams)

According to Servius' commentary on the Aeneid in Varro's version of the story the morning star ("quae Veneris dicitur" "which is said to belong to Venus") accompanied Aeneas until he arrived in Italy without ever vanishing, Servius also links the appearance of this star to Venus' promise to never leave Aeneas (Nusquam abero, et tutum patrio te limine sistam - You will nowhere be without me and will safely place you at your father's doorstep; Servius reads numquam - "never" - for nusquam).
