A star is a ball of very hot gas that shines by its own light. planets as you know, and our moon, too, shine only by light reflected from the sun, and planets shine with a steady light while stars appear to twinkle. This is caused by substances in the air between the star and the earth. The unsteady air bends the light from the star, and then it seems to
Why Does Our Sunshine?
Because it is a star! And not a very big or bright star at that. Compared to all the other stars in the sky, it might be considered medium-sized and medium-bright. There are millions of stars that are smaller than our sun. And many stars are several hundred times larger than the sun. They look small only because they are so far away.
Ever since the days of the Greek astronomers, some 2,000 years ago, the stars have been divided into classes according to their ‘magnitude”, or brightness. Another way of grouping stars is according to their spectra, or the kind of light that comes from the stars. By studying the differences in these spectra, the astronomer may learn about the colors, be temperature, and even the chemical composition of the stars.
Does Earth Shine Like Star?
Speeding outward from the Earth and moon system, you pass the orbits of the planets Mars, Jupiter, and Saturn. From all of these worlds, Earth looks like a star
Why do stars shine only at night? This is a no-brainer: the stars don’t actually shine. They are just twinkling bright points of light, and the same is true of other celestial objects such as planets. This is because sunlight is scattered by particles in our atmosphere to make it visible, but once it enters space, it is no longer affected by the atmosphere.
Let’s start with the obvious question: how long do stars shine? The answer has been “Forever” for as long as anyone has been able to accurately measure it, which is pretty much as far back as anyone can reliably date. But there’s a lot less certainty about how long the universe itself will last, and that’s because we’re limited by the amount of time we’ve been able to accurately measure since the Big Bang.
The most beautiful star is a tricky question to answer. There are a few stars that are in the top 10, but the most beautiful star is probably the Sun, since it is much closer to us (and is also often referred to as the home star), and so gives us a very close look at our world. The second most beautiful star is probably Sirius, the brightest star in the sky. The third, fourth, and fifth most beautiful stars in the sky are Alpha and Beta Centauri, the red dwarf system closest to us, and so giving us a close look at the life around it. Other stars, however, have been considered beautiful due to their size, brightness, distance, and other factors.
