[net.space] Name of the sun

billp@bronze.UUCP (Bill Pfeifer) (08/16/83)

	The discussion about a possible planetary system around Vega
brought up the question about names.  "Sun" is just a generic term that
applies to the star closest to the planet on which one stands.
	A few years back I spoke with someone who insisted that the name
of our star is "Copernicus".  Can anyone confirm or deny?  I have not heard
anyone use that name since.  The same person said that the name of our
galaxy is "Bruno Galaxy".

Since I have my bachelor's and graduate work in astronomy/astrophysics,
I feel compelled to relate the rules for using terms like "solar
system", "sun", etc.  The main rule is that there are no firm rules,
at least to the best of my recollection.  For example, when one 
says "stellar system" one can be referring to a binary or larger
system of stars going around a common center of gravity or
one can be talking about a whole galaxy.  The "Sun" is Sol but
to a person standing on say Vega X "the sun" is Vega.  It's
sort of like "South" meaning Dixie and "south" meaning the
the direction.  Take things in context and there won't be
problems.

If somebody wants to talk about planets of Vega, I would use the
term "planetary system" but mainly just because I'm a heliocentric
chauvinist.  The *context* in which I heard "stellar system" used always
implied stars, not planets.

Aside from the astronomer, the only Copernicus I know is a satellite.
Our galaxy has always been known to me as "The Milky Way" or "The
Galaxy" (being chauvinistic again).  Just be thankful it wasn't named
Ford.

Hey UTASTRO! Any comments?

I would tend to agree with Jeff Johnson.  Based on this, I looked in 
Webster's New Collegiate Dictionary for support.  The following is an
excerpt from that entry.

sun
1 a: the luminous celestial around which the earth and other planets
revolve. . .
b: a celestial body like the sun

There's also a lunar crater named Copernicus....

It is appropriate to name our galaxy after Giordano Bruno and our sun after
Copernicus, especially since Bruno was burned at the stake for holding these
views while Copernicus just barely escaped this fate by dying before his book
was published.

Have these names been officially adopted by the IAU or are these
*suggestions* ?

When we discuss the "name of the Sun" or "Snickers" or that
stuff, what is the name of the body that officially sanctions
these names?

	Not afraid to ask a dumb question.

Bill Pfeifer suggests that the name of our sun is "Copernicus," and the
name of our galaxy "Bruno Galaxy."  These are indeed the proper names
for those entities.

I believe the first person to suggest these names was Andrew Galambos,
an astrophysicist and social theorist.  His rationale is that, in
science, things are properly and usually named after their discoverers
or inventors or other primary contributors.  Copernicus is the first
person to correctly, permanently identify for all mankind the nature and
relative position of the sun; likewise, Giordano Bruno was the first to
identify that the visible stars, the visible components of our galaxy,
are suns like our own.  Who better to credit than these two men?
