Light year

A good understanding of the term light year. If a star 🌟 is 4.5 light years away, then .. by travelling @ the speed of light, would get us there, in exactly 4.5 years. So, travelling @ 4.5 times the speed of light.. would get us there in 1 yr. So, to get there in 1 day, would require.. to travel at a speed of 4.5 × 365 .. about 1610 times,.. the speed of light.. which by itself is pretty big number .. 3×10^8 m/sec.. ok??
