To determine which stars are above you, you can use various online tools and mobile apps that provide real-time sky maps. These tools can help you identify constellations, major stars, and planets that are visible with the naked eye. Here are some resources you can use:

• Stelvision: This website offers an online sky map that allows you to easily locate the main stars and planets visible in the sky. You can also observe that all the sky appears to rotate around Polaris, the North Star. The website explains that every evening, the stars in the sky return to the same place 4 minutes early because the Earth’s movement in its orbit around the sun gives us a slightly different background of stars each night. These 4 minutes represent the difference between the length of a day (24 hours) and that of an earth’s rotation (23 hours and 56 minutes). You can scroll the sky day by day with the next day button to see that the stars are rising a little earlier each evening.

• Time and Date: This website offers an interactive night sky map that simulates the sky above your location on a date of your choice. The map shows the planets that are visible tonight, as well as their rise and set times. You can also see the altitude and direction of each planet in the sky. The website provides tips on how and where to see "shooting stars" from your location.
