Facts about our Sun, including its distance from Earth, what the Sun is made of, and how long it would take to drive there (hint: a long time!).
Learn the differences between our Earth, the Sun and the Moon. Then explore how together they create day and night and our different seasons with their orbits.
Size: Earth has a diameter of 7,926 miles (12,756 kilometers). Distance from the Sun: Earth is the third planet from the Sun, which is about 93 million miles (150 million km) away.
The sun is really, really big. The sun lies at the centre of the solar system where it dwarfs all other objects. It holds 99.8% of the solar system’s mass and is roughly 109 times the diameter of the ...
As they rush from the sun, CMEs can send huge shockwaves through the solar wind. If a CME collided with Earth, its particles could pack enough power to fry electronics in orbit and on Earth's surface.
A sunspot four times the size of the Earth is crossing the sun right now. The mark is so big it can be seen with the naked eye, said one astronomer. But it's very dangerous to look straight at the ...
The sun is sporting a giant coronal hole that could fit 20-30 Earths across, back-to-back. Coronal holes blast rapid solar winds into space that travel 500-800 kilometers per second. The winds are ...
The sun has developed a massive “hole” 20 times larger than Earth, marking the second such occurrence in a week. The coronal hole is unleashing solar winds of 2.9 million km/h toward Earth ...
Let's say we want to build a model of the sun and Earth alone. Earth has a radius of about 6,371 kilometers (3,959 miles), but let's represent this with a marble 1 centimeter in diameter.
