A complex system of stars just under 100 light years
from the Earth's Solar System. The
two major components are Rho Capricorni A and Rho Capricorni D. These form a distant pair in comparison with most
multiple systems: they are at least an eighth of a
light year from one another. This is the most prominent pair of
stars in a quintuple system close to the
Ecliptic in the constellation of
Capricornus.
The apparent magnitude for the system as a whole is +4.8, making it just bright
enough to be seen as a faint point by the naked eye. Its absolute magnitude
is somewhat brighter, +2.4, and if it lay 10 parsecs from the
Earth, it would appear as bright as Merak, the southern
star of the two Pointers in the
Plough.
