The Ideal Planetary Model

Specifications For the Purpose of a Most Stable and Moderate Climate, Globally

In our quest to explore space, especially for the purpose of finding equivalent or even better planets for human habitation, then it helps to have a base line set of planetary parameters for the most ideal planet to live on. And then we have a reference point. Earth, with its ever warming climate and deteriorating conditions, perhaps even irreversible now, is by far, no longer the "ideal model" to look for in the cosmos. The set of planetary parameters, below, is what we would look for in our quest for other worlds that would be very close to the most hospitable for human habitat.

Our model planet starts with a 243 day "year", only two thirds the Earth year; and its orbital radius from the warming star is about 2/3 that of the earth from the sun (somewhat similar to Venus). The warming star of this model is about 44% the size and/or photo/thermal radiation output as the Sun. (Due to the inverse square law of thermal and light radiation - i.e., an object receiving only 1/4 as much radiation for every doubling the distance of the object from the source - the warming star needs only, and should only be, 44.4% output as the sun. This radiation would be from a combination of size and brightness of the star, and put an equivalent amount of surface radiation on our planet as received by the earth). The rotational period (day length) is the same as Earth's: 24 hours. A shorter year (eight months long) accomplishes the effect of lessoning sub-tropic heat shock. This intelligent design recognizes the need to shorten the time during the long solstice periods when the star's rays hover around the sub-tropic latitudes too long and create land/oceanic heat shock, which causes hurricanes, - as happens on Earth.

The climate benefits of this model are best achieved with a planet, of which, the axial tilt is much less than Earth. A tilt of no greater than 14 degrees N & S latitudes is needed. This mild seasonal lighting (the angle of the star's rays) received in temperate and polar latitudes doesn't create the extremes in heat and cold for summers and winters. In addition, the topographic features of this planet provide for seas at the poles down to 65 degrees latitude N & S, and, a mountainous, high altitude land belt around the equator to at least 17 degrees N & S latitude. The temperate latitudes alternate with one or two equal areas of land
