You must decide Vesta up simply in binoculars or any small telescope. As an added bonus, Neptune lies 8° north-northeast of Vesta, whereas mighty Jupiter — seen to the bare eye however stunning by means of binoculars or a scope — is 16° northeast.
You possibly can even web a second asteroid close by: Some 10.7° northeast of Vesta is 3 Juno. Notice, although, the fainter, Ninth-magnitude world is a bit tougher to identify. You’ll discover it some 4.5° west-northwest of 4th-magnitude Iota (ι) Ceti.

The truth is, decrease energy is best, as it’ll present each without delay, sitting some 0.5° aside and located about 4.5° northwest of 4th-magnitude Miram (Eta [η] Persei).
Additionally listed as NGC 869 and NGC 884, the previous sits simply east of the latter. Each include wealthy fields of stars, with in a different way coloured suns readily obvious all through.
