1.30 · Geographical Objects and Features · Heavenly Bodies
star, planet a star or a planet Since in JUD 1:13 godless people are likened to ‘wandering stars’ or ‘planets,’ it may be best to introduce this expression by a simile, for example, ‘they are like wandering stars.’ In some languages there is a serious difficulty involved in translating ἀστὴρ πλανήτης as ‘planet,’ since the planets or their courses through the heavens are regarded as beneficial. In JUD 1:13 the focal meaning is upon the heretical nature of these godless persons who do not keep on the right course. It may therefore be necessary to translate ἀστέρες πλανῆται in JUD 1:13 as ‘stars that do not stay where they should stay’ or ‘... do not remain in their right places.’ See also 15.26.

Collocation: ἀστὴρ πρωϊνός
morning star, bright star in the morning sky (an idiom, literally: morning star) a planet which is conspicuous in the morning sky (usually either Venus or Mars) In REV 2:28 the singular pronoun αὐτῷ refers to any and all of the persons in Thyatira, and therefore it is usually best rendered as plural. A literal rendering of REV 2:28 may be confusing, since it would suggest that God would be handing over the morning star to persons in Thyatira. A more satisfactory rendering may be ‘I will cause the morning star to shine upon them’ or possibly ‘I will bring light into their hearts.’

ἀστήρ. Syli 140" (late iv/B.C.), a list of payments on account of the temple at Delphi, has το[ῦ €]vA[C]vou ἀστέρος τοῦ παρδείγματος ““{π6 pattern of the wooden star’: see note. In OG/S 194 (i/B.c.) it is said of the Egyptian Amon Ra that ὥσπερ λαμπρὸς ἀστὴρ Kal δαίμων ἀγαθὸς τοῖς ἀπελπίἵουσι]ν ἐπέλαμψε. The use made of the same figure in the Apocalypse undoubtedly suggested the fourth century epitaph which Ramsay (Zee, p. 366) discovered on a stone now built into the wall of an early Turkish Khan in Lycaonia— Νεστόριος πρεσβύτερος ἐνθάδε kite ἀστὴρ ὃς ἐνέλαμπεν ἐν ἐκλησίεσιν θεοῦ.
