If planet X exists and it is 20 times further than Neptune (which has a distance of 30 AUs and an orbital period of 165 years), what would its orbital period be? What would its speed need to increase by to escape the solar system? Please show and explain as much work as possible. Thank you and you are appreciated!

Astronomers discover a new, potentially habitable planet: Planet X. Planet X’s sun is 50% dimmer than ours, but the distance between Planet X and its sun is half of the distance between Earth and our sun (0.5 AU), meaning it has a solar constant of 1225 W m-2. a. If the planet’s albedo is 10% (a = 0.1), do you think there could be liquid water on this planet? Calculate the blackbody temperature of Planet X, and explain why/why not....
