Multiply that by all the seconds in one year, and you get 5.8 trillion miles (9.5 trillion kilometers). Just for reference, Earth is about eight light minutes from the Sun. A trip at light speed to the very edge of our solar system – the farthest reaches of the Oort Cloud, a ...
So using the fastest thing possible, light, and how quickly it travels in a period of time, we have a measurement method for long distances. For example, in one second light travels ~300,000 kilometers. That means it can get to the Moon in about 1.25 seconds. The distance is therefore...

An astronomical unit (AU) is exactly 149,597,870,700 meters (92,955,807 miles or 149,597,871 kilometers), according to the International Astronomical Union (IAU). This is roughly the average distance between Earth and the sun. Astronomers use astronomical units to describe how far away obje...
How big are we in the universe? As such, one light-year is the equivalent to 9 trillion kilometers / 6 trillion miles, and our Universe is93 billion light-years in diameter. That's how big our Universe is, and that's not even the end of it. ...
The Universe Circle Fact :Distance between Earth and Sun : 150 million kilometers. This is just the description of the Universe that can be observed by us using the given technology. This is how tiny we are that we cannot be depicted graphically on the same plane! Tiny, yet capable of ...
The sun is just one of about 200 billion stars in the Milky Way, our home galaxy, which is just one galaxy in the universe. So, how many galaxies are in the universe? In this article, we'll find out how galaxies were discovered and what types exist, what they're made of,...
