Once you have a graph, hover over each point to see the planet's name and a description!



There's a lot of terminology on this page - here are some quick explanations

ExoplanetShort for "extra-solar planet"; a planet going around a star other than our Sun
[M Jupiter]
[R Jupiter]

As a point of reference, Astronomers usually compare an exoplanet's mass and radius to Jupiter
PeriodThe amount of time (in Earth days) that the planet takes to go around its star
Semimajor axisA measure of how far away the planet orbits from its star.
[AU]1 AU is the distance the Earth is from the Sun - used as a point of reference when measuring a semimajor axis

Research Questions!

With just a little exploration, you can answer all sorts of interesting questions

Which exoplanet in the dataset has the highest mass?
What year did exoplanet discovery really take off? When do planets discovered using the Kepler space telescope start showing up? How did the mass of planets that we were able to discover change over time?
What's the average semimajor axis for planets discovered? Are there any planets that are orbiting around their stars about the same distance as Earth? (1 AU or 1e+0 on the axes...).
How has the average semimajor axis of discovered planets changed over time? What does that say about exoplanet finding techniques?
