When do you see the most stars?
It is summer in the northern hemisphere and winter in the southern hemisphere. For the northern hemisphere, summer is night, and we are facing the center of the Milky Way. In winter, we face the edge of the Milky Way, so for the northern hemisphere, there are the most stars in summer. In summer, the earth just turns between the sun and the Milky Way, and the Milky Way belt appears above our heads, so that we can see many stars. When winter comes, the earth moves to the position between the sun and the edge of the Milky Way, and fewer stars are seen at the edge of the Milky Way, so it is related to our Milky Way that we see more stars in summer than in winter, because almost all the stars we see are stars of the Milky Way. There are at least 654.38+00 billion stars in the whole galaxy, which are roughly distributed in a pie-shaped sky. The center of the pie is thicker than the surrounding area, and it takes 654.38 million+years for light to travel from one end of the pie to the other. Our solar system is a member of the Milky Way. The solar system is not located in the center of the Milky Way, but about 25,000 light years away. When we look towards the center of the Milky Way, we can see that there are dense horizontal stars and most of the Milky Way in the center, so we can see more stars. When you look in the opposite direction, you only see the edge of the Milky Way, and you see far fewer stars. The earth goes round and round the sun. In summer in the northern hemisphere, the earth moves between the sun and the center of the Milky Way. The main part of the Milky Way, the galactic belt, only appears in the sky above us at night. In other seasons, the densest part of this star appears in the daytime, early morning and dusk. Sometimes it is not in the center of the sky, but near the horizon, so it is not easy to see. Therefore, we see more stars in summer nights than in winter nights.
