The planetary radius is 0.84 and mass is 0.57 Earth standard; a planet of normal density.

"We don't have evidence that if their cycles return, their bone is going to return to normal density."

In these conditions, lines can form which are suppressed at normal densities.

The grey curve is the true density (a normal density with mean 0 and variance 1).

This density appears qualitatively very similar to a normal density.

On May 11, the solar wind dropped to a few percent of its normal density and its speed was cut in half.

In these conditions, atoms behave quite differently and lines can form which are suppressed at normal densities.

Gas in this acoustic path will be briefly compressed to hundreds or thousands of times its normal density.

The normal density of troops required for a vigorous offensive, he reminded his caller, was five or six to a meter.

They were on the far side of the second habitat, away from the entrance, where the normal density of human beings was at its lowest.
