An organism living in space would need several important characteristics:

  1. A mechanism for deriving energy from light (eg photosynthesis). This would be essential as there are very few sources of chemical energy in space. So you would have to make your own.
  2. It would have to be big, really big. A large creature (a few hundred meters) would be better able to gather nutrients and elements necessary for its continued growth and survival. If it were small, it simply wouldn’t be able to gather enough material or sunlight to sustain itself. This seems counterintuitive compared to creatures on a planet. But consider how easily a small plant can die compared to a large one. The big one can muster up enough energy and nutrients to ward off even a major injury or drought. A small plant would die in a few days.
  3. It would have minimal movement capacity. Movement requires propulsion, and a space organism would not want to waste resources to propel itself. Probably the only propulsion it would be able to manage would be reproduction through division and then separation. Internal movements may be perfectly possible, and change reasonably. However, this also needs to be minimal and only to a certain extent to maintain internal heat.
  4. He needs to live close to a star. It is unlikely that an organism can sustain itself outside of a star system. If it did, it would need to hibernate, as the energy it receives would be minimal. An organism traveling between stars would likely need to be many kilometers in size.
  5. It wouldn’t be smart. Intelligence really needs a lot of energy…so it’s not something an organism like this could handle.
  6. May harbor symbiotic organisms. If one organism evolved in space, it would not be unlikely that others would. Likely, such an organism would harbor a series of organisms that are symbiotically involved in its survival.
  7. It would have to have evolved on an asteroid. Life like this could not evolve in space itself, so it must evolve into a larger object like an asteroid. It is more likely that it evolved on a planet as a microbe, then was ejected into space on a rock due to a meteorite impact. From there, it would likely engulf the rock and asteroid to grow and eventually into a space organism.
  8. Reproduction would be asexual. I alluded to this earlier. It would likely reproduce asexually. Space is simply too large for a species to depend on finding a sexual partner, and the cost of producing sperm and eggs to cover a large area of ​​space would be highly detrimental. This would likely involve budding or separation from the ‘mother’.
    Another possibility is that such an organism could generate spores when approaching a star. Spraying spores in many directions would not only allow propulsion, but the spores would float until they came into contact with an asteroid, then slowly engulf the asteroid for nutrients before becoming a single creature.

So… yes, it is possible that there is a space organism. I would imagine a large, leaf-shaped organism. more like a plant than an animal.
