'The fixed one', shown to the bride on the wedding night (dhruva-darśana) as an emblem of constancy. In the historical period Dhruva = Polaris, but scholars note that at plausible dates of the ritual's origin (2nd-1st millennium BCE) no bright star stood at the pole: α Draconis (Thuban) was pole star c. 2800 BCE, and Polaris only closed on the pole in the last ~1500 years. Dhruva may therefore be an idealized 'fixed point' of the sky, an earlier pole star remembered, or a faint near-polar star. Parallel rite with the mantra dhruvám asi: Śāṅkhāyana GS 1.17.2-4, tr. Oldenberg: 'Let them sit silent, when the sun has set, until the polar-star appears. He shows her the polar-star with the words, Firm be thou, thriving with me! Let her say, I see the polar-star; may I obtain offspring' (same source URL).

Attestations
New Purāṇic attestations, each adding something: (a) BP 5.23.1 places Dhruva 1.3 million yojanas above Saturn's region, circled by five star-deities — the fullest positional statement; (b) BP 5.23.5 fixes him at the tail-TIP (pucchāgra) of the Śiśumāra, more precise than Viṣṇu P. 2.9's 'in the tail'; (c) VP 1.12.90-92 grants him a station above Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, all asterisms and the Saptarṣis. On identification, note honestly that Polaris was NOT at the pole when these texts were composed — precession puts Thuban near the pole c. 3000-2500 BCE and Polaris only in the last few centuries; R.N. Iyengar and R.S. Hariharan argue the figure preserves a memory of Thuban, which remains a reconstruction.
Amarakośa gives Dhruva one synonym, the patronymic Auttānapādi. Colebrooke's gloss is 'The pole', and his footnote is explicit that it may mean 'the north pole itself', distinguishing the mythological Dhruva son of Uttānapāda from the astronomical usage in which 'Uttānapāda is Ursa minor' — which is direct support for the caveat already on file that Dhruva may name the pole rather than a star. Separately, the Nānārtha-varga (3.3.792) records a second technical sense: dhruva also denotes a class of asterism (bha-bheda), the dhruva/sthira group used in muhūrta.

SAGE/ADJECTIVE-VS-STAR DISCRIMINATION: 'dhruva' occurs 458× in the Mahābhārata and 48× in the Rāmāyaṇa, and the overwhelming majority are the adverb/adjective 'certainly, fixed' or the boy-king Dhruva. Three occurrences are unambiguously the pole star. (a) MBh 6.3.16, in the omen list, where 'Dhruva, blazing, turns terribly anticlockwise' — the whole surrounding list is planet-on-nakṣatra portents and Ganguli renders 'the constellation Dhruva'. (b) MBh 12.126.25, a simile: the munis 'sat down placing him in front, as the seven ṛṣis do Dhruva' — which presupposes the Saptarṣi circling the pole. (c) Rāmāyaṇa 6.4.43, where the paramarṣis 'all shine circling Dhruva to the right (pradakṣiṇa)' — the clearest statement of circumpolar rotation in either epic; Dutt renders 'all the rishis, pure and furnished with lustre, go round Dhruba'. CAUTION on a passage that looks stellar but is not: MBh 5.109.13 'atra yajñaṃ samāruhya dhruvaṃ sthātā pitāmahaḥ' is read by Ganguli adverbially ('the Grandsire dwelleth in the vicinity of Yajna'), not as the pole star, and should not be counted. The α UMi identification is anachronistic for the epic period and is carried over from the Purāṇa/lexicon entries.
Devanagari from Sanskrit Wikisource; identical with GRETIL (taṃ prītiviśadair netrair anvayuḥ paurayoṣitaḥ / śaratprasannair jyotirbhir vibhāvarya iva dhruvam).
Not the adverb dhruvam 'certainly' (which Kalidasa also uses freely): here dhruvam is the object of the nights' gaze, and the nights are personified as looking with 'autumn-clear luminaries' (śarat-prasannair jyotirbhiḥ) for eyes - i.e. the whole starry sky turned toward the one fixed star. Nandargikar translates 'the polar star'. The image is astronomically exact: every star in the sky circles Dhruva.

The dhruva-darsana, the wedding rite in which the groom shows the bride the Pole Star as an emblem of constancy - here rendered as a triple pun on dhruva ('by her CONSTANT husband, for the sight of DHRUVA'). This is the ritual context that keeps Dhruva alive as a named star in classical India, and it is the one place in Kalidasa where a star is not a simile but an object physically looked at by a character.
Devanagari from Sanskrit Wikisource; word-for-word identical with the GRETIL (Sansknet) IAST e-text. BOTH witnesses misprint the verse number as 11.2, duplicating the preceding stanza - the verse is in fact 11.3. Both also carry the corrupt 'व्यस्तमेथ्' / 'vyastamet' at the end of the first line.
A genuine naked-eye observation, and the most astronomically interesting line in Magha: the circle of the divine sages (the Big Dipper) shines MORE BRIGHTLY (sphuṭataram) than Dhruva, who is alpamūrti - 'of small body', i.e. FAINT. Sanskrit poets almost never concede that the pole star is dim; Magha does. He then likens the Dipper to the great CART (śakaṭa) whose end was tipped up by the infant Krsna's kicking foot - a wagon-figure for Ursa Major arrived at independently of the Greek and Latin plaustrum.
