Most conversations about space and the solar system overlook Earth. Nonetheless, since humans live there and Earth is a planet like any other, we know a lot about it. Two thirds of the surface of the Earth is covered with water, with high peaks and deserts making up the remaining third. That is the standard of living for people on Earth.There are an estimated 1.75 million other species on Earth,..
Venus is closer to Earth than Mercury, but that doesn't mean it's a good place to live. Believe it or not, Venus is hotter than Mercury!People once thought that Venus, the second closest star to Earth, was the sister star of Earth. This is because it is relatively close, but it is almost the same size as Earth. But other than that, they have little in common. Venus' atmosphere is filled with thi..
Since Mercury is the planet closest to the sun, it will be examined first in our solar system. The only planet smaller than it is Pluto, making it the second-smallest planet in the solar system. It is also uninhabitable, in contrast to Earth, which offers a suitable environment for humans. Specifically, due to its low mass, it has minimal attraction (引劫, attraction) and is unable to retain the a..
We live on Earth, which is a planet, as you are undoubtedly aware. However, do you know what constitutes a planet and how it differs from a star? Just as Earth, Venus, and Jupiter orbit an elliptical path around stars, planets are masses of gas, metal, and stones that revolve around stars (like a star that emits light on its own, like the sun). Put differently, a planet is any entity that is inc..
Because the sun shines so brightly during the day, it is difficult to think of it as a star. But the sun's status as a star is unquestionably true. This star, which is responsible for 99 percent of the solar system's mass, governs planets and numerous other celestial bodies. How large is the sun, then? And just how hot is it?The sun's surface temperature is roughly 6,000°C, while its core temper..
A binary star system is made up of two stars that are drawn to one another and orbit a common center of gravity at regular intervals. The eclipse binary, spectral binary, and orbital binary are the three different categories of binary stars. While an eclipse binary is invisible to the naked eye, even with the largest telescope, an orbital binary can be observed with one. Binary stars, which appe..
Most likely, you do not know much about planets or stars. I will tell you about stars and planets first, though. But you should never forget that the sky is home to a vast array of other objects. Furthermore, galaxies that gather a large number of stars will be covered. Specifically, we will examine our galaxy—a galaxy to which we are members. And what else will we discover? In this course, amon..
In a clear night sky, stars make up the majority of the bright spots visible. With the planets among them. Shooting stars, comets, satellites, and other objects we will learn about in the future can be seen engraved on the night sky alongside the planets and stars. Furthermore, space contains a diverse range of gases and dust particles. The universe includes all living things on Earth, including..
As if someone had spilled ink, look up into the pitch-black night sky. What comes to mind first when you look up at the astonishing, mysterious, and magnificent night sky? People have always been enthralled with the wonders of the night sky, and you are no exception.What is the glow of crystals in the night sky? Why do they constantly travel across the sky at night? How does the moon move across..
