And then they were heading out, their trajectory scarcely bent by the planetary mass.

The difference comes from the way in which planetary masses are calculated.

As such, the planetary masses form a self-consistent set, which is not always the case for more recent data (see below).

These observations revealed that a body of planetary mass was orbiting the star.

In these books, however, planetary masses were used rather than smaller projectiles.

These five have planetary mass, and so would be considered (dwarf) planets if they were in direct orbit about the Sun.

From out of the mist, a planetary mass appears.

Because of the gravity problem, it couldn't have reversed through the planetary mass.

In contrast, the Earth's iron core is about 30 percent of the planetary mass.

We are not close enough to any planetary mass to prevent that.
