The Earth does not merely stand in the same spot in space and spins but is always rushing eastward along in its orbit around the sun. As a result, the stars appear to rise, cross the sky and set four minutes earlier each night. The Earth completes a single turn on its axis, not in 24 hours, but 23 hours 56 minutes. What patterns in the stars do we notice when observing the night sky?īased on this information, which constellation(s) will be visible next summer in the Northern Hemisphere?Īs our Earth whirls through space around the sun, its motions cause night and day, the four seasons, and the passage of the years.

Finally, in the fall, the Great Square of Pegasus comes into view. In the spring, the constellation of the Sickle of Leo, the Lion, is present. The same spot in the summertime revels the stars of Scorpius. ![]() In the winter months, stargazers in the Northern Hemisphere look into the night sky and see Orion the Hunter.

For comparison, the Sun’s magnitude is −27, Venus can reach −4.2-depending on its phase and distance from Earth-while a full Moon is –12.7. the western sky after dark its magnitude is, by definition, zero. You can see Vega right now by looking high i. The magnitude scale uses a star called Vega, in the constellation of Lyra, as the standard reference star. getty How is a star’s brightness measured?
