Data from space telescopes show a comet's orbit will cross Earth's path, leaving behind a trail of dust and debris. What prediction can scientists make from this observation?

When Earth passes through dust and debris left along a comet’s orbit, particles enter Earth’s atmosphere and burn up, appearing as meteors. This can produce a meteor shower, so the prediction is that a meteor shower will occur when Earth crosses the debris trail. The observation does not imply lasting changes to Earth’s orbit or magnetic field.
