Multi-planetary federated Knowledge Graphs are also a possibility. But
is it real?

In practical terms, I would say the definition should be specified
using standards only.
Something like "RDF datasets exposed on distinct base URIs as pairs of
Linked Data and SPARQL endpoint services, with enabled resource
dereferencing and federated query (SERVICE) features."

There is an increasing need to account for the provenance of data and include it so that the knowledge can be assessed by its consumers in terms of credibility and trustworthiness. A knowledge graph can answer what it knows, and also how and why it knows it.
