Earth's diameter is about 12,700km. This looks roughly 30 times that, so we'll say 380,000km across, or a circumference of about 1,200,000km (compared to earth's measly ~40,000km).
This puts the overall size somewhere between Jupiter and the sun (probably closer to the sun).
In terms of volume, you could fit about 10,000 standard earths inside the hollow ice ball.
