    Lots of interesting findings:

    The Big Picture

    6,065 confirmed exoplanets across 4,524 star systems – we've barely scratched the surface of our galaxy's ~200 billion stars

    – 2016 was the golden year with 1,496 discoveries in a single year, thanks to the Kepler mission's data processing

    – Transit method dominates (73.8%) – watching stars dim as planets pass in front is our best planet-finding technique

    Planet Diversity

    Super-Earths/Mini-Neptunes are most common (42%) – a planet type that doesn't exist in our Solar System.

    Only 3.7% are smaller than Earth – small planets are hard to detect, so there are likely many more

    678 "Hot Jupiters" – gas giants orbiting closer than Mercury, some completing a year in just hours!

    Extreme Worlds

    Shortest orbit: 0.09 days (2.2 hours!)

    Longest orbit: 1.1 million years – this planet has orbited its star perhaps 4,000 times since the dinosaurs

    Hottest planet: KELT-9 b at 4,050K – hotter than most stars!

    Lightest: 0.02 Earth masses (smaller than our Moon), Heaviest: 30 Jupiter masses

    And more.

    1. > small planets are hard to detect, so there are likely many more

      With Solar System asteroids happens a similar story. The distribution by size is skewed due to this effect.

    2. there was such a tremendous spike in 2014 – 2018. i remember hearing a lot of space news about “potentially habitable” planets back then, no wonder considering the data from the graph.
