diameter

Take the milky way: Up to 200,000 light years in diameter, containing some 100 to 400 BILLION stars.

This star is 24 times larger than our sun, 30 million kilometer in diameter.

The first step in an HDD installation is to drill a pilot hole, a small diameter borehole that will guide the rest of the project.

Again, it's a lightweight object that's really bouncy to encourage randomness but the actual inner diameter of the ring is really close to the outer diameter of the bottle.

Banging pipes inside your walls can sound a bit spooky, but for large diameter pipelines that can be hundreds of kilometers long, that surge in pressure from a change in momentum can cause major damage.

Let’s do a quick calculation: if you have pipeline carrying water that is 1 meter in diameter and runs for 100 kilometers , the mass of water in the pipe is about 80 million kilograms.

The smallest known black hole has 2.7 times the mass of the sun which works out as a sphere around 16 km in diameter, large enough to cover Paris.

These rigs can be tiny machines used to get a small fiber-optic line under a roadway or colossal contraptions capable of drilling large-diameter boreholes for thousands of feet at a time.

The Milky Way is not alone together with the Andromeda galaxy, and more than fifty dwarf galaxies,it forms the Local Group, a region of space about ten million light years in diameter.
