Arcturus is the brightest star in Bootes, and the fourth brightest star in the whole sky. It is a very large ("supergiant"!) star, with a bright orange-red color. Bootes was identified with
a farmer who plows the land during spring. The Romans believed that
Bootes was the herdsman of the seven oxen represented by the seven
stars of the Big Dipper.

Arcturus is a bright red supergiant star with a diameter nearly 20 times that of the Sun and a brightness more than 100 times that of our Sun. Since it is only 36 light-years away (close for a star!), it appears as the brightest star in Bootes, and, in fact, the fourth brightest star in the sky.
Bootes was identified with a farmer who plows the land during spring. The Romans called
Bootes the Herdsman of the Septemtriones, that is, of the seven oxen
represented by the seven stars of the Big Dipper, which was seen as
the cart or the plow.

The name Bootes is derived from the Sumerian Riv-but-sane,
which means the "man who drove the cart". So Bootes was identified
with a farmer who plows the land during spring. The Romans called
Bootes the Herdsman of the Septemtriones, that is, of the seven
oxen represented by the seven stars of the Big Dipper, which was seen
as the cart or the plow.
