If the planet passes directly in front of the sun, a solar transit occurs.

My understanding is that they spot planets by looking for drop in light intensity when the planet passes in front of the star.

The figure shows the times at which the planet passes from one sector to the next.

Stars with planets may also show brightness variations if their planets pass between the earth and the star.

The planet, which transits its host star, completely passes across the face of Kepler-28 in 2.77 hours.

A "transit" is a period of time when a planet passes in front of a star.

Three planets passed that one before it came to us.

If a planet and a moon passed in front of a host star, both objects should produce a dip in the observed light.

When the same juxtaposition occurred again, many years later, the planet would pass to the third sun, and so eventually back to its first partner.

If the eccentricity was actually this high, the planet would pass through the asteroid belt and clear it out within about ten thousand years.
