The night sky on your birthday: September 10
September 10 is day 254 of the year. Here is what the sky holds for everyone born on it — and a way to get the real sky above the exact place and hour you were born.
The Sun's constellation on September 10
On your birthday the Sun stands in front of Leo, even though horoscopes call September 10 Virgo: the zodiac signs were fixed about 2,000 years ago and the sky has drifted since (precession of the equinoxes). Because the Sun is in Leo, that constellation is hidden in daylight on your birthday: you see it best around six months later.
