Canopus
réalta
(Athsheolta ó Suhail)
Is é Canopus an réalta is gile sa réaltbhuíon theas Carina agus an dara réalta is gile i spéir na hoíche ag teacht tar éis Sirius. Tá méid radharcach de -0.74 aige agus dearbhmhéid de -5.65. Tá Canopus ina shárfhathach de chineál speictreach – F sa phríomhshraith. Samhlaítear é a bheith bán leis an tsúil nocht in ainneoin go dtugtar “bán bhuí” mar dhath dá leithéid sin réaltaí. Tá sé suite i bhfad sa leathsféar theas ar dhíochlaonadh -52'c' 42’ agus ar cheartéirí 06u 24.0n.
