When the Enterprise-B was launched in Earth-orbit, it was only 3 lightyears away from two transport ships captured in the Nexus. That means the Nexus was the closest out-of-system object.

However, there were no other ships available. Additionally, the Nexus is said to periodically appear roughly every 39 years, but apparently no-one knows about it on earth.

Is there any in-universe explanation for these apparent discrepancies?

    Tempted to close as a dupe of Why is the Federation so poorly patrolled?. The Enterprise is always the only ship in range because it's the ship that the movie is about.

    I've voted to close. Although they're somewhat related, there are actually several questions here.

The Nexus is a travelling energy ribbon

The Nexus is not stationary. It is a travelling "energy ribbon". It reappears every "39.1 years" in our galaxy (according to Data in the film) and there is no reason for it to appear in the same spot twice.

Presumably, when it appeared 3 light years away from Earth, that was the first time it had appeared there. There is no reason why Starfleet scientists should have known about the Nexus already.

Dr. Tolian Soran, who was exposed to the Nexus during that incident and subsequently became obsessed with it, had learnt enough about it to be able to chart its course and knew with enough precision when and where it would appear next — in the Veridian system, outside Veridian III (nowhere near Earth).

Finally, the fact that the Enterprise-B was the only starship in range of the Nexus is unremarkable. Starfleet's primary mission is exploration and, at any given time outside of war time, most of the fleet is committed to deep space. Earth would mostly be serviced by cargo ships, passenger transports (e.g. to the lunar and Martian colonies and to Jupiter Station), and fixed-position defence infrastructure.

  • I'm not so sure that there wouldn't be any other ships around Earth... but if we assume it took longer before that call came through than it looked, you could say they were too far for an immediate response. Commented Jul 22, 2016 at 7:38
