Sentences with phrase «dust near a star»

Like planets, dust near a star is hard to see.

Some planets are so near their star that they are losing mass too rapidly to have been planets for very long.14 Besides, their rocky cores would have melted before the planet's evolution could begin.15 Others are too far from their star and the dust near the star needed to grow a planet.
