The sun is made mostly of hydrogen and helium and is much hotter than lava. When lava first erupts from a volcanic vent, it is usually at temperatures between 700 and 1,200 °C. It is the center of our solar system. On a hot sunny day, you are about 150 million kilometers away, so that is about a billion times further than if you are 150 meters from the lava! Summer is officially here, which means it's time to go back to sun, sweat, and the outdoors. All of Kepler’s best capabilities have converged to yield the first solid evidence of a solid planet orbiting a star other than our Sun. Measuring the temperature of lava. The Sun is a hot ball of glowing gases. The sun, a massive nuclear-powered star at the center of the solar system, generates the heat and light that sustain life on Earth. There are lots of stars, but the Sun is the closest one to Earth. Hawaiian lava (basalt) is usually around 1100 C. Volcanoes such as Mt. The sun is *very* hot. Despite being coldest to the sun, Mercury is actually cooler than Venus due to its slow rotation and thin atmosphere. The daytime temperature’s expected to be more than 2,500 degrees Fahrenheit, hotter than lava flows here on Earth. The temperatures of lavas vary depending on their chemical composition. Eight planets move around the Sun. We call that an orbit. St. Helens erupt lava … The Sun is a star. Lava, when first exuded from a volcanic vent, is a liquid at temperatures from 700 °C to 1,200 °C (1,300 °F to 2,200 °F). There is no lava on the sun. Sun is hotter than Lava . The lave feels hot because (a) you are close to it and (b) it puts out a lot of infrared, (much of which is absorbed from sunlight by the earth's deep atmosphere). It keeps our planet warm enough for living things to thrive. In the hunt for an Earth-like planet outside our … Lava is molten rock expelled by a volcano during an eruption. Christiansen, U.S. Geological Survey, January 9, 1973. Photograph by R.L. Think about that for just a second… rock that is so hot it has melted into a liquid… Fabulous! Imagine a lava planet, with rocks raining down and wind howling at thousands of miles per hour. Magma is molten rock below the earth's surface. When compared to the average temperature on Earth, the other planets can clearly be seen to be far outside our understanding of life supporting temperature ranges. But how hot is the sun? No! It gives us light so we can see. It is the smallest exoplanet (a planet located outside our solar system) discovered to date. At peaks of 15 million degrees Celsius, our sun is the definition of too hot to handle, but scientists have been able to exceed this temperature regularly. Lava is molten rock.
