In the star system of Bray-Ali (this is the name of the star, which is a hypothetical star, and this star is 15% larger in mass than the Sun), there are several planets. Planet Flufferton is the 1st planet from the star, and is located at 1AU. Planet Mogu is the 2nd planet from the star at 2AU and the planet Shadow is the 3rd planet from the star at 2.8AU. Planet Fluffeton shows some craters, with many mountains and smooth. Planet Shadow’s surface appear to be heavily cratered, but planet Mogu’s surface appear to be very smooth. Judging from this information alone what can you tell me about these planets (surface age, presence of atmosphere, possible habitability and geologic activities). Explain your reasoning for your assessments.
