All questions can be answered by how durable the outer covering is. If it is extremely durable, it can survive an asteroid strike (plus the hydro-static skeleton works well as a shock absorber) and can maintain its shape regardless of size.

But since it's an alien creature that we know nothing off, we could still postulate that it is extremely durable.
