What does a light year represent?

A light year is the distance light travels in vacuum during one Julian year, roughly 9.4607 × 10^15 metres, used mainly in astronomy.

What is the Earth's polar radius?

Earth's polar radius is the distance from Earth's center to its mean geographic pole, approximately 6,356,752.314245 metres, used in geodesy and mapping.

Why convert light years to Earth's polar radius?

Converting helps relate immense cosmic distances to a familiar Earth-based measurement, making astronomical scales easier to understand.

Can I use this conversion for precise astronomy work?

No, this conversion is primarily conceptual and illustrative; precise astronomy requires direct cosmic distance units.
