Quote context

[...]

- This was Bronson's first discovery, Bellus, a star, a dozen times larger than our Earth.

- Bellus has been approaching Earth at tremendous speed.

- Bronson's second discovery, a new planet. Bronson named it Zyra, and his measurements show this new body revolves around Bellus more rapidly than Earth revolves around the sun.

- Hmm, this is in the constellation of Scorpio.

- Dr. Frye, notice the position of these new bodies.

- Yes. Yes, I see.

- But here again, Bellus and Zyra have changed position.

- Now, just how fast they've been moving, and their eventual destination are among the mathematical problems now being determined by our differential analyzer. We'll have the results in a few hours.

- Zyra is about the same size as our Earth.

- Both these bodies are coming into our solar system. If Bronson's readings are correct, they will destroy the Earth.

- How far away from us are they?

- The calculator will be precise. I would estimate about three billion miles.

- Billion? Let people start worrying 100 years from now.
