One of the sky's nicest gifts this month is an easy way to find and track the large asteroid 4 Vesta. This space rock remains within 1 binocular field of the 4th-magnitude star Alpha Piscium, which lies halfway up in the southeastern sky during early evening.
From a suburban backyard, you can spot the 7th-magnitude asteroid without much effort. Apart from Alpha, only three other stars in the area shine brighter than Vesta. From December 7 to 9, Vesta appears near the vertex of an equilateral triangle of these stars, the brightest of which is Alpha itself.
