Answer 2

Ответ:

Звезда – это небесное тело, в котором происходят термоядерные реакции. В результате этих реакций выделяется энергия, дающая свет. Следовательно, мерцающие светящиеся шары, многие из которых мы наблюдаем, это и есть звезды. Планета – это небесное тело, в котором термоядерные реакции не происходят

Answer 3

#### Difference between a Star and a Planet Stars and planets are celestial objects that exist in our universe, but they have distinct characteristics that set them apart. Here are the key differences between stars and planets: **1. Formation and Composition:** - **Stars:** Stars are formed from clouds of gas and dust called nebulae. The gravitational collapse of a nebula leads to the formation of a star. Stars primarily consist of hydrogen and helium, which undergo nuclear fusion in their cores, releasing vast amounts of energy in the form of light and heat. - **Planets:** Planets are formed from the leftover material after the formation of a star. They are typically composed of rock, metal, and gases. Planets do not undergo nuclear fusion and do not emit their own light. **2. Size and Mass:** - **Stars:** Stars are much larger and more massive than planets. They can range in size from small dwarf stars, such as red dwarfs, to massive giants, such as red supergiants. The size of a star determines its brightness and temperature. - **Planets:** Planets are relatively smaller and less massive compared to stars. They can vary in size from small rocky planets, like Earth, to gas giants, like Jupiter. The size and mass of a planet determine its gravitational pull and atmospheric conditions. **3. Light and Heat:** - **Stars:** Stars emit their own light and heat through the process of nuclear fusion. The energy generated by the fusion reactions in a star's core is what makes it shine. - **Planets:** Planets do not generate their own light. They reflect the light emitted by their parent star, making them visible in the night sky. Planets receive heat from their parent star, which determines their temperature and climate. **4. Orbits:** - **Stars:** Stars do not orbit around other celestial objects. They are fixed in space and serve as gravitational anchors for planets and other objects in their vicinity. - **Planets:** Planets orbit around stars in elliptical or nearly circular paths. The gravitational pull of the star keeps the planet in its orbit. **5. Number in a Solar System:** - **Stars:** A solar system typically consists of one star at its center. The star provides light, heat, and gravitational stability to the planets and other objects in the system. - **Planets:** A solar system can have multiple planets orbiting around a star. The number of planets in a solar system can vary, and each planet has its own unique characteristics. It's important to note that there are also objects called "brown dwarfs" that fall between the size of a planet and a star. Brown dwarfs are often referred to as "failed stars" because they do not have enough mass to sustain nuclear fusion in their cores.
