What is a mini-Neptune?
Group of answer choices
An exoplanet the size of Earth which appears to be habitable.

2. Over several months an astronomer observes an exoplanet orbiting a distant
star at a distance of 5.934 AU. Its orbit period was projected to be 3.875 years.
Convert the orbit radius to meters and period to seconds. Use this information to
calculate the mass M of the star in kg and solar mass units (Mo).

- H5. A star with mass 1.05 M has a luminosity of 4.49 × 1026 W and effective temperature of 5700 K. It dims to 4.42 × 1026 W every 1.39 Earth days due to a transiting exoplanet. The duration of the transit reveals that the exoplanet orbits at a distance of 0.0617 AU. Based on this information, calculate the radius of the planet (expressed in Jupiter radii) and the minimum inclination of its orbit to our line of sight. Follow up observations of the star in part reveal that a spectral feature with a rest wavelength of 656 nm is redshifted by 1.41×10−3 nm with the same period as the observed transit.
