Its shape was of a 5-point star, each point having its own unique geological and physical features, therefore considered a separate region of Númenor and had separate names:
- Forostar (Northlands)
- Andustar (Westlands)
- Hyarnustar (Southwestlands)
- Hyarrostar (Southeastlands)
- Orrostar (Eastlands)
- Mittalmar (Inlands)
The central region of Mittalmar contained the region of Emerië, a grass land with many sheep, and the sacred mountain Meneltarma, standing in the very center of the island. It was the highest location on the entire island and was a holy place devoted to Eru Ilúvatar. It was said that on a clear day the 'far-sighted' might see Tol Eressëa, the island east of Valinor proper which along with it comprised the Undying Lands.
The lower slopes of the mountain, the Tarmasundar, were gentle grass-covered, however, near the summit the slopes became more vertical and could not be ascended easily. The kings later built a spiral road to the peak, beginning at the southern tip of the mountain and winding up to the lip of the summit in the north.
The only other known mountain on the island was Sorontil, in Forostar.
Númenor had only two rivers: Siril which began at Meneltarma and ended in a small delta near the city of Nindamos, and the Nunduinë, which formed the lake Nísinen before reaching the sea in the Bay of Eldanna near the haven Eldalondë.
The island itself was tilted southward and a little westward; the northern coasts were all steep sea cliffs.
 Plant life
Númenor contained many species of plants that could be found nowhere else in Middle-earth, for many of them were given to the Númenóreans from the Valar in Aman. Most important of these was the White Tree that dwelt in the King's Palace at Armenelos. A seedling from it was later planted in in the Court of the Fountain in Minas Tirith, Gondor.
The other parts of Númenor contained many types of plants, many unique to each of the promontories of the island. Andustar contained great forests of beech and birch at the higher ground, and oak and elm forests are lower altitudes. The eastern part of Hyarnustar, being warm and fertile, had great vineyards.
The greatest delight of the Númenóreans, however, were the trees given to them by the Eldar. They grew mostly in the Western portion, Andustar. They are often remembered in song and lore, and few have flowered east of Númenor.
In Hyarrostar grew the tree Laurinquë, which the Númenóreans loved because of their flowers. They believed that it came from the Great Tree of Valinor,
The word is actually the allative form of the Quenya word elen meaning "to (a) star". The "longer" name Elenna-nórë is glossed as "Land of the Star", literally "Starwards-land". The island was named so as the Edain colonists sailed "starwards", following the Star of Eärendil.
Robert Foster mistakenly identifies the word as being the "essive" form of elen. Essive is a grammatical case that exists in Finnish (but not in Quenya), and is marked by the ending -na, like the Quenya allative.
Tolkien never drew a map of Arda showing where exactly in Belegaer, or relative to Middle-earth the island of Númenor stood but there are some narrative hints.
While sailing for Lindon, Vëantur had to fight the north and east winds suggesting the the island was south of the latitude of Lindon. It is also mentioned that Vëantur was accompanied by (apparently migratory) birds in autumn and spring.
The Downfall of Númenor, while also causing important loss in Lindon, most of all filled much of the Bay of Belfalas so that the city of Pelargir was left far inland. This may suggest the island was more or less around the latitude of the Bay of Belfalas. As vineyards are attested in the eastern part of the Hyarnustar, Didier Willis notes that adequate climatological conditions for viticulture are quite strict and estimates the island to be located around 40° N, indeed facing the Bay of Belfalas.
As for the distances, we are told simply that the island was closer to Valinor than Endor. It was said that from Meneltarma, the keen-eyed Númenóreans could sometimes get a glimpse of Avallónë; the Fall of Númenor came 39 days after Ar-Pharazôn left, but his actual voyage could be shorter.
Didier Willis estimates that as Vëantur could sail directly from Númenor to Lindon - not needing to find a closer coast and follow it up to his destination - the island was close enough to Lindon, with a realistic distance between 2000 to 3000 km.
Karen Wynn Fonstad placed the island in her Second Age maps around the latitude of the Bay of Belfalas, but without giving any reasoning or calculations. It approximates the Númenórean ports of Vinyalondë, Pelargir and Umbar on Middle-earth. Her map shows the distance between the Island and Eressea approximately 1700 km.
