If a sizable rouge planet hit one of the rocky planets such as Mars, large chunks of debris would come shooting out of the collision, a very high chance that a few pieces would land on Earth potentially creating another mass extinction; similarly to the other rocky planets such as Venus and Mercury. So even an "invisible" rogue planet could act as a gravitational lens—or micro-lens, as they can be so small. 8 years ago. So, yes … theoretically. Change the Earth’s orbit, and the conditions for life won’t be so great. What If The Sun Was Smaller Than The Earth? Adobe Stock. Sort by .

Nomad planets range in size from Pluto-esque (5.5 times smaller than Earth) to as big as Jupiter (11 times bigger than Earth). Solar energy, on the other hand, would be considered very inefficient in the wintertime but could be used very effectively during the short blaze of summer. But what is a rogue or nomad planet, and why should we not be afraid of something that big hurtling through space? They’re Out There. Global extinction could be right around the corner. The effect of that rogue planet would be enough to slightly disrupt other planets' orbit if it passes close and could disrupt the entire solar system.
