The "end of [12th]house" doubt, and stellium?!

The "end of [12th]house" doubt, and stellium?

Some, but few sites tell me that my sun and neptune are in the 12th house, whilst others tell me that they're on the 1st. Is it trying to imply that I may be on the "cusp" of the 1st and 12th house combined? or that im now on the 1st house? I've also recently came across 'stellium', I know I have them on my chart, but what I would like to know is what of the specific effects on my chart indicate? Here's my chart :

Sun Capricorn 8°53'27 end of house 12 direct
Moon Taurus 24°00'53 in house 5 direct
Mercury Capricorn 13°26'31 in house 1 direct
Venus Aquarius 10°56'26 in house 1 direct
Mars Scorpio 24°20'59 in house 11 direct
Jupiter Aries 20°11'13 in house 3 direct
Saturn Sagittarius 25°21'51 in house 12 direct
Uranus Sagittarius 27°36'40 in house 12 direct
Neptune Capricorn 7°45'11 end of house 12 direct
Pluto Scorpio 11°58'34 in house 10 direct
True Node Pisces 26°50'48 in house 3 retrograde

Thanks in advance!

Edit : last line, 'stellium' not 'specific'. I didn't check the mistakes, and forgot to add the word 'stellium'. I didn't want my whole chart to be indicated, just the stellium aspects.

Well, from what you've cut and pasted, the Sun is at the "end of house 12" at 8 Cap 53 and Mercury is in the 1st house at 13 Capricorn 26

Since you did not post your house cusps, we have to assume that you must have Capricorn rising, and were likely born around Sunrise (Sun on the Ascendent).

The reason you may get conflicting statements over 12th house vs 1st house is that if the Sun is close enough to the Ascendant, which is also the 1st house cusp, we would read it as "Sun in the 1st house" as well as "Sun conjunct Ascendent". This makes you a "double Capricorn" by the way.

A "stellium" is just another way of saying usually more than two planets are conjunct. In this case you have a Sun/Mercury/Neptune conjunction or "stellium" in Capricorn.

Technically, the definition of a stellium is:
Stelliums are made up of Aspects -- Conjunctions, to be exact. A Stellium refers to three or more Planets that form a series of Conjunctions in an astrological chart, regardless of whether the Planets span into two Houses or if they are in different Signs or the same Sign. Whatever the combination may be, their combined energies create a particular focus, making a Stellium deserving of attention.

What's important is that we would read the influence of all three of these planets linked together, and especially since this was on your Ascendant at the time of your birth.

The combination of Sun, Mercury and Neptune especially on your Ascendent may make you interested in such things as movies or the music industry. You likely have a very keen ear for music, if you don't enjoy performing it yourself. You could be artistically gifted in some manner, and Mercury involved in the Stellium would help you express this gift outwardly as well, especially on the Ascendant.
