Astronomers estimate that the universe could contain up to one septillion stars – that’s a one followed by 24 zeros. Our Milky Way alone contains more than 100 billion, including our most well-studied star, the Sun. Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. […]

27 de jun. de 2019 · The Short Answer: Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Many other solar systems have multiple suns, while ours just has one. Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on the surface. Our Sun is a bright, hot ball of hydrogen and helium at the center of ...
15 de mar. de 2016 · Our Solar System. Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun. Neptune is the farthest.
There are five officially recognized dwarf planets in our solar system: Ceres, Pluto, Haumea, Makemake, and Eris. The inner, rocky planets are Mercury , Venus , Earth, and Mars. These worlds also are known as terrestrial planets because they have solid surfaces. Mercury, Earth, and Mars are currently being explored by spacecraft.
A star system is a group of planets, meteors, or other objects that orbit a large star. While there are many star systems, including at least 200 billion other stars in our galaxy, there is only one solar system. That's because our sun is known by its Latin name, Sol. The solar system includes everything that is gravitationally drawn into the sun's orbit.
Hace 5 días · The Sun’s gravity holds our entire solar system together. Our solar system is even named after the Sun (the Latin word for Sun is “sol”). Heat from the Sun makes Earth warm enough to live on. Without light from the Sun, there would be no plants or animals—and, therefore, no food and we wouldn’t exist. Heat and light might be important ...
