That's gotta be right or it's a close answer. I think most of my answers have been pretty good.

It's not a comet. Comets are not very "heavy" in the cosmic scheme of things and really don't have neighbors as such. However, the object's designation does happen to be A1.

darn

well is it the A1 point of the NGC 3603

What exactly do you mean by "point"?

I guess I mean part because there is A1 , B and C

Spica is a B1 designation. Try to think more serious, something that is a star designated as A1 (non-vegetarian sauce).

Actually I think maryccc has it.

Yes, but what are they? It would be nice if you would provide an explanation that fits the clues given.

Well, she did bludgeon out the answer but she failed to explain why it is correct.

That is a saucy number. I missed its announcement, somehow. [I see my intuition was wrong, but I had a hunch it was. ]

Congrats, marycc (apparently).

What the ...

A1 is the most massive star known. It is the first star to have a confirmed mass greater than 100 times that of the Sun. It's binary secondary is also very massive, as are some nearby stars in the open cluster/emission nebula NGC 3603. Formulaterp already supplied one of the links that I was going to cite. Here's another: http://www.usatoday.com/tech/science...ive-star_N.htm

The saucy in saucy (not so) little number refered to the star's namesake, i.e., A1 Steak Sauce.

Well, the star is clear, but ...
... I've never heard about this brand.

Sorry I didn't mean to be a bludgeoner. I mean that A1 is a hotter and more massive star than a F, G, K or M Star. The Sun is a G star and Rigel is a B star so this A1 star wouldn't be as strong as Rigel. But it would be more massive than the sun. The hottest star out there would be an O star.
The order from Hottest to Coolest is O, B, A, F, G K M

The C Stars would be stars with a surplus of Carbon I believe.

Yes, but the labels A1, B, and C in this case don't refer to the spectral classifications of these stars.

Well, it is in general hotter (the scale isn't ordered by temperature but presence and absence of particular spectral lines, but those criteria coincide to some extend in many cases). The relation to mass holds only on the main sequence. Red (super-) giants are usually M class but can be much more massive than K, G or A dwarves, for Antares I find M class and at least 15 solar masses. They just puff up, shedding only little mass, and cool down on the visible surface, which makes them M. White dwarves on the other hand are usually hot and to the left on the spectral scale but not very massive, for Sirius B I find B class at solar mass.

At this HRD the former record holder in our milky way is Eta Car, the "X" at the upper left at (B0,-10), the extended (puffed up and rather thin) biggies are at the top right, VV Cep being one of the largest at all.

I haven't read everything about the NGC3603 issue, but it seems to me they just labelled the items sequentially starting with A for the brightest (maybe appending a number in case of evidence of it being a multiple itself), that's common practice for multiples. It's got nothing to do with spectral class. Some prominent examples:

Alpha Cen: A is G class, B is K class
Procyon (Alpha CMi): A is F class, B is a white dwarf (looks like A class)
Keid (40 Eri): A is K class, B is a white dwarf, C is M class

Maryccc, it's your turn to pose a question.

There is a scene where a someone in space gets a hole in his suit. As the air leaks out, and his body is exposed to a vacuum, we watch in horror through his faceplate as he swells, and explodes. What was the year and name of this movie?
