A big lens gathers the light and directs it to a focal point and a small lens brings the image to your eye. © 2000 HowStuffWorks A telescope is an amazing device that has the ability to make faraway objects appear much closer. Telescopes come in all shapes and ...
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...

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 ...
How big is a red dwarf star? How big is the International Space Station? How wide is the asteroid belt in kilometers? How wide is the Hubble Space Telescope? How fast does a black hole spin? How big is Jupiter's magnetosphere?
How far is the planet Saturn from Earth? Approximately how long does it take the Sun to orbit the Milky Way galaxy? How wide is the Hubble Space Telescope? How far is the planet Pluto from the sun? How long is the Kuiper belt in kilometers?
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...
It is the largest object in the solar system, but how big is the sun when compared to the rest of the stars in theMilky Way galaxy? The sun is classified as medium-sized among these hundreds ofbillions of stars. Radius, diameter and circumference ...
like most other gas giants in the galaxy. For WASP-193b, these gases likely form a hugely inflated atmosphere that extends tens of thousands of kilometers farther than Jupiter’s own atmosphere. Exactly how a planet can inflate so far while maintaining a super-light de...
What you're seeing is a portion of theMilky Way, our home galaxy, which measures 100,000 light-years in diameter. (A light-year is the distance light travels in one year — almost 6 trillion miles, or 9.5 trillion kilometers.) Its core hosts a supermassive black hole — a giant gravi...
