What is the Transit Method in exoplanet detection?

Back

The Transit Method involves observing the dimming of a star's light when a planet passes in front of it, allowing astronomers to infer the planet's size and orbital period.

What does a light curve represent in astronomy?

Back

A light curve is a graph that shows the brightness of a star over time, which can indicate the presence of orbiting exoplanets through periodic dips in brightness.

Front

What is an orbital period?

Back

The orbital period is the time it takes for a planet to complete one full orbit around its star.

Front

How can the size of an exoplanet be inferred from a light curve?

Back

The size of an exoplanet can be inferred from the amount of light it blocks from its star during a transit; a larger planet will block more light.

What is the significance of Kepler's discoveries?

Back

Kepler's discoveries have significantly advanced our understanding of exoplanets, revealing the diversity of planetary systems and the potential for habitable worlds.

Front

What is the relationship between a planet's distance from its star and its orbital period?

Back

According to Kepler's Third Law, the square of a planet's orbital period is proportional to the cube of its average distance from the star.

What is the difference between Kepler-11b and Kepler-11g in terms of orbital period?

Back

Kepler-11b has the shortest orbital period among the Kepler-11 planets, while Kepler-11g has a longer orbital period.

Front

What factors can affect the accuracy of measurements in the Transit Method?

Back

Factors include the star's variability, the presence of other planets, and observational noise.

Front

What is the approximate orbital period of Kepler-7b?

Back

~5 Days.

Front

How do astronomers determine the size of an exoplanet like Kepler-9b?

Back

By analyzing the light curve and measuring the amount of light blocked during its transit.
