78 light-years away, and also 78 times as luminous as the

Sun. In 1925 a bright nova, RR Pictoris, flared up in

the Painter, and remained fairly prominent for some time

before fading back to obscurity.

Volans(originally Piscis Volans, the Flying Fish). A small

constellation which, rather confusingly, intrudes into

Carina between Canopus and Miaplacidus. It contains

little of interest, though Áis a wide, easy double.

Puppis. The Argo’s poop, part of which is sufficiently

far north to rise in British latitudes though the brightest

star, ̇, cannot do so. ̇is a very hot 0-type star, 63,000

times as luminous as the Sun and therefore the equal of

Rigel in Orion; it is 2400 light-years away. L^2 is a semi-

PUPPIS

regular variable with a range of magnitude from 3.4 to

just below 6; V Puppis is of the ‚Lyrae type, with a range

of about half a magnitude.

There are only three Messier objects in Puppis,

because the rest of the constellation never rises over

France, where Messier spent all his life. All three are

open clusters. M46 and M47 are neighbours, more or

less in line with ‚ Canis Majoris and Sirius. M93, in

the binocular field with ÍPuppis, is fairly bright and

condensed. Admiral Smyth, the well-known last-century

amateur astronomer, commented that the arrangement of

the brighter stars in M93 reminded him of a starfish. The

distance is 3600 light-years.
