What does Space Explorer do?
Space Explorer is an ad-free utility for exploring confirmed exoplanets, host star systems and mission candidates. Search a subject, read its measured properties and discovery facts, view timelines and charts, and compare up to four planets.
Are candidates the same as confirmed planets?
Confirmed planets and candidates remain separate. TESS, Kepler and K2 mission candidates are identified as candidates, and false positives are labelled as such. A candidate listing does not establish a confirmed planet.
How can I compare planets?
Compare up to four planets, using Earth and Jupiter as reference points. Property charts bring measurements together, while ranges and uncertainties remain visible. Distances use parsecs with light years for comparison.
Where does the information come from?
Space Explorer uses VISINVOKE-hosted snapshots of NASA Exoplanet Archive tables. Planet, system and candidate pages retain discovery and parameter references, and the app shows the snapshot date. This describes a dated dataset rather than continuously live observations.
How are measurements presented?
Ranges and uncertainties stay attached to measured properties. Minimum masses and other mass types are named. Composite values can combine different papers, with their source disclosed. The page does not label a planet as habitable.
Is Space Explorer free, and where do I use it?
Space Explorer is free with your VISINVOKE account and has no adverts. Use it through Desktop Command Centre on Windows and Android. VISINVOKE is not affiliated with or endorsed by NASA, Caltech or IPAC.
