Why exoplanets are hard to see directly

An exoplanet is a planet orbiting a star outside our Solar System. Direct images are very rare because the planet is extremely far away, so the angular separation between star and planet is tiny.

Step-by-step lessons on AQA A Level Physics Detection of exoplanets (A-level only). Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
