5 · The Sun wields a huge influence on Earth. Its gravity holds our planet in its orbit, and solar energy drives the seasons, ocean currents, weather, climate, radiation belts, and auroras on Earth. The solar wind, a flow of charged particles from the Sun, constantly bombards Earth''s magnetosphere, a vast magnetic shield around the planet.

The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies. It is by far the most important source of energy for life on Earth. The Sun has been an object of veneration in many cultures. It has been a central subject for astronomical research since antiquity.
The solar system is a collection of planets, moons, asteroids, comets, dust and gas that orbit our local star, the sun. It includes the rocky inner planets Mercury, Venus, Earth and Mars; the gas
Venus is the sixth largest planet in the solar system. Venus is about the same width as Earth, and has an equatorial diameter of about 7,521 miles (12,104 kilometers). For this reason, Venus is sometimes known as Earth''s twin. Venus is the second planet from the Sun, orbiting at an average distance of 67.2 million miles (108
The solar wind blasts from the sun to the edge of the solar system. Other particles form coronal loops. Coronal loops are bursts of particles that curve back around to a nearby sunspot. Near the sun''s
Solar System Exploration. During June, NASA, NOAA, and people around the world are celebrating Earth''s Ocean as part of National Ocean Month.NASA has been observing Earth''s ocean from space for more than 20 years. Now, NASA is launching missions to explore other ocean worlds.
The solar system is enveloped by a huge bubble called the heliosphere. Made of charged particles generated by the sun, the heliosphere shields planets and other objects from high-speed
The Sun is the star at the heart of our solar system. Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest bits of debris – in its orbit.
In Depth. The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It''s about 93 million miles (150 million kilometers) from Earth and it''s our solar system''s only star. Without the Sun''s energy, life as we know it could not exist on our home planet.
The sun is a yellow dwarf star in the center of the solar system, and it is the largest, brightest and most massive object in the system. The sun formed around 4.5 billion years ago. At that time

Meet the Sun. The Sun is a yellow dwarf star at the center of our solar system. Earth and all other objects in our solar system orbit around the Sun due to gravity – the Sun contains over 98% of all mass in the solar system and so exerts a strong gravitational pull. Like other stars, the Sun is a dense ball of gas that creates energy through
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

The Sun is the Solar System''s star and by far its most massive component. Its large mass (332,900 Earth masses), which comprises 99.86% of all the mass in the Solar System, produces temperatures and densities in its core high enough to sustain nuclear fusion of hydrogen into helium. This releases an enormous amount of energy, mostly radiated into space as electromagnetic radiation peaking in visible light.
The Sun is the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together. Everything in our solar system revolves around
