An tAra

Tá **an tAra** ar cheann de na 88 réaltbhuíon nua-aimseartha a nglacann an tAontas Réalteolaíoch Idirnáisiúnta leo; tá sé ar cheann chomh maith de na 48 réaltbhuíon a d'aithin Tolamaes sa dara haois. Is é **Auriga** an t-ainm Laidine a thugtar air, a chiallaíonn *[[ara]]*.

## Príomhghnéithe
* ε Aur: tá an réalta seo ar cheann de na déréaltaí is aistí sa spéir. Is déréalta uraitheach í; tá an tréimhse fhithise 27 bliain ar a fhad, agus maireann gach urú 18 mí nó mar sin. Is ollfhathach leathbhuí, den aicme speictreach F0, an réalta infheicthe, ach tá an compánach dofheicthe de chineál anaithnid.

* ζ Aur: is déréalta uraitheach aisteach í seo freisin, dá ngairtear freisin **Sadatoni**. Tá a tréimhse 972.176 lá ar a fhad. Is ollfhathach flannbhuí an phríomhréalta, den aicme speictreach K4; agus is réalta an phríomhsheichimh an coimhdire, den aicme speictreach B7.

## Réada suntasacha domhainspéire
* M36, M37, M38: trí réaltbhraisle oscailte mhóra gheala; is féidir na trí cinn a fheiceáil le chéile sa réimse radhairc céanna i bpéire déshúiligh leathanréimse.

* NGC 2281: réaltbhraisle oscailte.

* NGC 1664: réaltbhraisle oscailte.

* NGC 1907: réaltbhraisle oscailte.

* IC 405: réaltnéal geal.
