So long as the two extremes of brightness allow a single planet in a single orbit to remain habitable (the bright-high variance being summer and the dim-low variance being winter), then all we need is a non-predictable variable star and the problem is easily solved. Frankly, people give way too much emphasis to orbital changes. | |
