In our night sky, some stars appear as part of a symbolic image or pattern called a constellation. Why do some constellations appear all year long, and others appear only for a few months each year?

• Constellations are different sizes and only the largest appear all year long

• Constellations in the southern and northern hemisphere are seen at different times of the year due to changes in Earth's axis

• Constellations appearance varies greatly during the year due to the changing seasons and times for day and night

• Constellations located above the poles are visible all year, while others appear at different times due to Earth's orbit

Which is the best explanation about the Moon?

• The Moon shines from different parts of the sky at different times of the month

• The Moon grows a little each day until becoming full and the gets smaller each day. This pattern is repeated each month.
