The sun is the star at the center of the solar system. It is the Earth’s primary source of light and heat. The sun is a medium-sized star and is about halfway through its life. Here are 3 facts about the sun.
The sun is huge: its diameter is about 109 times that of Earth. Sun’s diameter is 109 times that of Earth’s. The sun is about a million times brighter than the full moon. One million suns would be needed to equal the brightness of the full moon.
3 facts about the sun
The sun is really, really hot
The sun is really, really hot. In fact, it’s so hot that it can actually cause physical pain. The sun emits a type of radiation called ultraviolet (UV) radiation, which can damage the skin and eyes. UV radiation is divided into three categories: UVA, UVB, and UVC. The sun’s rays contain all three types of UV radiation, but most of the UVB is absorbed by the atmosphere. That leaves UVA and a small amount of UVB to reach the ground.
The sun is really, really hot. In fact, it’s so hot that it can actually cause physical pain if you’re not careful. The sun is also the source of all life on Earth – without it, we wouldn’t be here. Finally, the sun is huge! Its diameter is about 109 times that of Earth, and it has a mass of about 333,000 Earths. The sun is made out of two main parts. The core, which is about 10 times the diameter of the Earth, is very hot and dense. It’s made entirely of hydrogen atoms that are packed together so tightly that they actually fuse together to make helium.
The sun is old
The sun is old. It’s estimated to be around 4.6 billion years old. The sun is about halfway through its life. It has another 5 billion years or so to go. The sun will eventually die. It will become a white dwarf.
The sun is one of the most important objects in our solar system. It is the largest object in our solar system. The sun is huge and so bright it’s hard to look at it with your eyes. The sun is a star and it gives off light and heat. The sun is huge and so bright it’s hard to look at it with your eyes. The sun is a star and it gives off light and heat.
That means that the sun has been around for nearly half the age of the universe. The sun is huge too. It’s about 1.3 million times the size of Earth and has a mass of 333,000 Earths. The sun is also pretty hot. The surface temperature is around 5,500 degrees Celsius (9,930 degrees Fahrenheit). But don’t worry, we’re safe here on Earth. The atmosphere protects us from the harmful rays of the sun.
The sun is also a dynamic and active star. It occasionally produces violent solar storms that can interfere with radio communications on Earth. The sun’s constant activity also causes it to change shape and size slightly during the course of its lifetime, although not enough to be noticeable from Earth.
The sun is bright
The sun is bright. Its luminosity is about 3.86 x 10 26 watts. The sun is the most important star in our solar system because it provides the Earth with light and heat. The sun is a medium-sized star and is about halfway through its life.
The sun is the star at the center of the solar system. It is the Earth’s primary source of light and heat. The sun is a medium-sized star and is about halfway through its life. It has a diameter of about 1.392 million kilometers and a mass of about 2 x 10 30 kilograms.
The sun is one of the most important objects in our solar system. It is huge and so bright it’s hard to look at with your eyes. The sun is a star and is huge and so bright because it’s so close to Earth. The sun gives day and night, summer and winter. It also gives us light and warmth.
There are 3 facts about the sun. The sun is a star that is located in the Milky Way galaxy. It is about 150,000 times the size of Earth and has a mass of about 333,000 Earths. It is an average distance from Earth of about 93.3 million miles and completes one orbit around the Milky Way every 250 million years. The sun is a main sequence G-type star and is part of the local spiral arm, the Orion Arm. It is about halfway along its life cycle and will live for another estimated 7 billion years.
The sun is about 93 million miles from Earth. The distance to the sun is not constant because Earth’s orbit around the sun changes slightly due to the gravitational pull of other planets, including Jupiter and Venus.
