The article states that only about 100 exoplanets had been discovered.

• A. True
• B. False
• C. Not enough information
• D. About 1,000

Answer: (B)

The statement is not accurate because the number of exoplanets known by many years into the field was already well above a hundred. Exoplanets are found using methods like watching for a star’s slight wobble (radial velocity) and detecting tiny dips in a star’s light when a planet passes in front (transits). These methods quickly built up a catalog: hundreds of confirmed exoplanets, and over time thousands, as surveys continued. So claiming only about a hundred had been discovered understates the actual count, making the statement false.
