HR 8799 e is a large exoplanet, orbiting the star HR 8799, which lies 129 light-years from Earth. This gas giant has 7.5 times the mass of Jupiter and 1.13 times its radius. Due to their young age, all four discovered planets in the HR 8799 system are large, compared to all gas giants in the Solar System.
The analysis highlights Art, Observations and Description as prominent areas in the source structure around HR 8799 e.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
