# HD 85512b

## Planetary Description

HD 85512b is an exoplanet classified as a "Super-Earth". It is a habitable planet with temperatures averaging at about 75F. Although it can be looked at as if it is too different from Earth, its the planet's similarities that make it suitable for human life.

• HD 85512b orbits an orange dwarf star named HD 85512 which has around 2/3 the mass of our sun
• The planet is classed as a Super-Earth, which are planets that have up to ten times the mass of Earth
• The planet was discovered in August 2011 by a Swiss based team of scientists using the radial velocity method of detection

## Problems and Difficulties with Planet

• HD 85512b would need a good amount of cloud cover in order for liquid water to exist on the planet
• The planet can be looked at as "Too Hot" and temperatures don't make it a habitable zone
• HD 85512b is approximately 35 light years from Earth so it would require a very efficient travel system to arrive safely and within a reasonable amount of time.

## How To Overcome These Problems

• HD 85512b would have to have 50% cloud cover
• The planet 's temperatures would have to be consistent and just right in order to sustain liquid water making it a habitable planet
• We would have to use an efficient travel system to arrive safely and within a reasonable amount of time.
