The planetary boundary layer is the part of the troposphere that is closest to Earth's surface and is directly affected by it, mainly through turbulent diffusion.

During the day the planetary boundary layer usually is well mixed, whereas at night it becomes stably stratified with weak or intermittent mixing.

The depth of the planetary boundary layer ranges from as little as about 100 meters on clear, calm nights to 3000 m or more during the afternoon in dry regions.

The study of other planets is usually called planetary science.

It contains no globular clusters, no planetary nebulae, and no open clusters.

Lifetime After a star passes through the asymptotic giant branch (AGB) phase, the short planetary nebula phase of stellar evolution begins as gases blown away from the central star at speeds of a few kilometers per second.

Planetary science (rarely planetology) is the scientific study of planets (including Earth), moons, and planetary systems, in particular those of the Solar System and the processes that form them.

There's actually a little read out down there of our planetary atmosphere, pressure and temperature.

) It is the prototype for a class of planets called hot Jupiters.

Other objects commonly observed in ultraviolet light include planetary nebulae, supernova remnants, and active galactic nuclei.

So if this limit exists, or if the limit of their derivatives exist, then this limit's going to be equal to the limit as x approaches infinity of the derivative of the numerator.

Mars had rivers, Mars had lakes, but more important Mars had planetary scale oceans.

Unlike Jupiter's, Uranus's aurorae seem to be insignificant for the energy balance of the planetary thermosphere.

Everything has its limit.

Can you take this biosphere, that has evolved on a planetary scale, and jam it into a little bottle, and will it survive?

Its bulk density suggests that it is similar in composition to the terrestrial planets, being primarily composed of silicate rock.

This result is supported by the observations made by the Keck telescope in 2002 and by evolutionary modeling.

The Atterberg limits are a basic measure of the critical water contents of a fine grained soil, such as its shrinkage limit, plastic limit, and liquid limit.

He argued (incorrectly) that a planetary conjunction could create a nova, which he linked to the Star of Bethlehem.

The Boomerang Nebula is a protoplanetary nebula located 5,000 light years away from Earth in the constellation Centaurus.

A multilateral limit may only be set if the participant has set at least one bilateral limit .

Thus, every ordinal is either zero, or a successor (of a well defined predecessor), or a limit.
