The star named Sirius has a declination of approximately -16°. ANSWER?

Yes, Sirius is 16 degrees south of the celestial equator. For an observer at 16 degrees south, Sirius would pass at the zenith (directly overhead) everyday. I live at 38 degrees north, so Sirius only reaches 35 degrees above my southern horizon.

South.

Declination is like latitude, but on the sky rather than the Earth's surface. It describes your position north or south. A "minus" sign indicates south declination (or latitude, for that matter).

The equivalent of east and west longitude on the sky is called Right Ascension, but that's given in hours/minutes/seconds, rather than degrees as on Earth's surface.
