Did the planets form before the sun
WebSep 25, 2014 · A team of researchers studying the origin of the water in our solar system has concluded that up to half of it formed before the sun itself was born—that is, in the cloud of dust and gas that was the progenitor of our solar system. If water can form in abundance in such clouds, then it may be found everywhere. WebVenus, the second planet from the Sun, and Earth are often called twins because they are similar in size, mass, density, composition and gravity. However, the similarities end there. Venus is the hottest world in the solar system, despite the fact that it is not the planet closest to the Sun. Temperatures reach 870 degrees Fahrenheit (465 °C),
