Do you use star charts?

How to use the starry sky chart:

When using the North Sky Star Chart, you should face the north so that the direction of the horizon on the star chart is consistent with the direction of the actual horizon. Hold the star chart above your head to view. At this time, the top of the arc on the star chart is the zenith position. Compare with the star chart. Look for constellations in the sky;

When using the southern star chart, the method is the same as using the northern star chart, but in the opposite direction.

Among the Big Dipper, the nearest one is 50 light years away from us and the farthest one is 150 light years away.

1 light year = 9,460.8 billion kilometers

The distance between the planets that make up the constellation remains unchanged and they are three-dimensional to each other.

The shapes we see are only the shapes we see on Earth.

The same constellation looks different from different locations in space.
