มีคำตอบเรื่องนี้จากโหรฝรั่ง เจ้าของเว็บไซต์ astroamerica ลองอ่านดูนะครับ แต่ยังไม่มีเวลาแปลเป็นภาษาไทย

"THIS past week a group of homeless astronomers in Minneapolis suckered the local paper, the Tribune, into running the old lie about Ophiuchus being the “13th sign of the zodiac.” Which got picked up by KSTP, the local TV station, and then by CNN, The Christian Science Monitor, The Huffington Post & everyone else. Somebody in nearby Baltimore made a
YouTube video in which he blamed the Astrology Center of America (that’s us, folks)
and told viewers to call our number. Which he gave. It promptly went viral & I got lots
of angry phone calls, before I got Google to remove it for violating my privacy. In response I sent the following to the Tribune. I would be most surprised if it was
printed:—

REGRET to report the article was wrong in all respects. The tropical
zodiac is based on the Earth-Sun relationship. Not on stars.

Zero Aries is defined as the Vernal Equinox.
Zero Cancer is the Summer Solstice.
Zero Libra is the Autumnal Equinox.
Zero Capricorn is the Winter Solstice.

All based on declination, not longitude. This was expounded by Ptolemy in his
Tetrabiblos, c. 140 AD, but it wasn’t his idea. It had already been in use for some
time prior. Please note that in Ptolemy’s day, the Sidereal & Tropical zodiacs were, to a
casual eye, identical.
There is a zodiac based on star positions, with Aldebaran as fiducial (marker). That is
the Sidereal Zodiac, in use in India. It is a radically different system that cannot be
compared to the Western Tropical Zodiac.
As none of the signs are based on stars (not in the Tropical system, nor the Sidereal),
use of this or that constellation is symbolic. Not actual. And always has been. In the
classical system there are 12 signs and seven planets. Extrapolated from these are not only
the calendar, but the seven day week and the 24 hour day. Seriously adding or subtracting
pieces would literally collapse human timekeeping. Sure you wanna do that?
Nor is the tropical system static. Because the Earth does not have a perfectly circular
orbit, some seasons are longer than others, and over the centuries, the dates of the
Earth’s perihelion and aphelion change. In 1838, perihelion was on January 2. In 2020,
perihelion will be on January 5 (precise times are available). (Source: Tables of Planetary
Phenomena 3rd edition, Michelsen/ Pottenger, Starcrafts Publishing, 2007) The tropical zodiac reflects this. The sidereal zodiac does not.
Which means some signs of the zodiac are actually longer in time than others.
Which means that a degree in the tropical zodiac is accurate, whereas a degree in the
sidereal zodiac is merely the annualized mean. From shortest “degree” to longest
“degree”, the difference over a year amounts to roughly 30 seconds of arc. Tropical shows
this. Sidereal cannot.
You can take the entire solar system, Sun, planets, moons, asteroids, you can drop them
into a distant galaxy far, far away, and the tropical zodiac will still be exactly accurate,
since it will still be based on the Earth-Sun relationship. Which is fundamental. The
Sidereal zodiac is relative. ALL Sidereal zodiacs (there are, let me see, the Fagan-
Bradley, Lahiri, Krishnamurti, Raman, Shill- Ponde & three or four others) are based on the
Tropical Zodiac. The fudge factor they all use is called the Ayanamsha. Which is a variable
that is subtracted from Tropical positions.
Any self-respecting astronomer KNOWS THIS, as it is nothing but the Earth’s own
orbital mechanics. You cannot send a space probe to the Moon, much less Venus or Mars,
unless you have mastered these essentials. The Jet Propulsion Lab in Pasadena has.
There are a group of astronomers who trot this story out every three or four years
or so. I heard it three years ago at a local high school in Edgewood, MD. I heard it
back in the mid-1990’s, I heard it back in the late 1980’s. It probably goes a lot further
back, because it’s guaranteed the astronomers behind it have learned nothing.
Nor do they want to.
In recycling this erroneous story, you have done a disservice to your readers as
well as launched a near panic in many quarters, as the phone calls I got on the 13th,
here in Maryland, will prove.
I am,

I run the Astrology Center of America, where
we keep track of things like this, in order to
spare the ignorant their embarrassment."
