Réaltra bíseach is ea réaltra Andraiméide, agus é le feiceáil i réaltbhuíon Andraiméide. Tá an réaltra seo suite faoi 2.2 milliún solasbhliain dínn, agus is é an réaltra bíseach is gaire dúinn. Cé is moite de Bhealach na Bó Finne féin, is é an t-aon réaltra bíseach is féidir a aithint ar spéir na hoíche gan úsáid a bhaint as gléasra cianradhairc ar nós na ndéshúileach nó an teileascóip. Tá Scamall Mór Magellan agus Scamall Beag Magellan le feiceáil chomh maith, ach ní réaltraí bíseacha iad. Ceann de réaltraí an Ghrúpa Áitiúil é. Is é an teileascóp is fearr a thabharfaidh léargas air, sin nó priontaí de ghrianghraif fhadnochta.

De ghnách, sílimid gurb é lár an réaltra seo an réaltra ar fad, ach le fírinne, cumhdaíonn Andraiméide seacht leithead na lánré d'achar na spéire, agus 300,000 milliún réalta ann ar fad. Tá dhá réaltra bheaga shatailíteacha aige, mar atá M 32 agus NCG 205, iad araon infheicthe le teileascóp beag. Is é Réaltra Andraiméide an réaltra is mó sa Ghrúpa Áitiúil, agus is é Bealach na Bó Finne is tánaiste dó.

Tá réaltra Andraiméide ag druidim isteach chugainn agus luas 300 ciliméadar in aghaidh an tsoicind (186 míle/soic.) faoi. Mar sin, tá sé ar an mbeagán réaltraí gormaistrithe ar an spéir. Má chuirtear gluaiseacht ár ngrianchórais féin taobh istigh de Bhealach na Bó Finn san áireamh, gheofar an toradh go bhfuil ár réaltra féin ag dul i dtreo Andraiméide agus luas 100 go 140 ciliméadar in aghaidh an tsoicind faoi (62–87 míle/soic.). Más é an t-imbhualadh atá i ndán don dá réaltra, titfidh sé amach i gceann trí mhíle milliun (10⁹) bliain. Sa chás sin, ceaptar go rachfaidh an dá réaltra le chéile le haon réaltra mór éilipseach amháin a dhéanamh. Is minic a tharlaíonn an cineál seo eachtraí idir réaltraí atá suite sa ghrúpa áitiúil chéanna le chéile.
