What is 2 Lupi

2 Lupi is a mature orange giant in the southern Wolf, a star that has already spent the hydrogen in its core and swelled many times the Sun's size. It shines with a warm tone, like aged amber, some three hundred light-years away. When this light began its journey, late Renaissance Europe was still lit by torch and candle, and no telescope worth the name had yet been imagined.

Where it is and when to see it

2 Lupi lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May, when it culminates around midnight.

From London it culminates about 8° above the horizon.
From New York it culminates about 19° above the horizon.
From Sydney it culminates about 86° above the horizon.

It can be seen from anywhere south of 60° N.

It ranks no. 20 in brightness among the 74 stars of Lupus in our catalogue. To find it, start from Alpha Lupi, the brightest: it lies about 19° away (a fist at arm's length covers about 10°).

The light you see today left it about 330 years ago.
