The night sky on your birthday: August 10
August 10 is day 223 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 August 10
On your birthday the Sun stands in front of Cancer, even though horoscopes call August 10 Leo: 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 Cancer, that constellation is hidden in daylight on your birthday: you see it best around six months later.
Overhead at midnight on August 10
- Northern hemisphere (40°N — New York, Madrid, Beijing): Cygnus, Lacerta, Pegasus and Vulpecula; brightest stars high up: Deneb (82°), Vega (60°) and Altair (54°).
