Although the light year is a
commonly used unit, astronomers
prefer a different unit called the parsec (pc). A parsec, equal to 3.26
light years, is defined as the distance at which 1 Astronomical Unit subtends an
angle of 1 second of arc (1/3600 of a degree) When we use the parsec for really
large distances, we often put a prefix in front of it - like kiloparsecs (kpc),
which are equal to 1000 parsecs - or Megaparsecs (Mpc), equal to a million
parsecs.
The Milky Way is about 1,000,000,000,000,000,000 km
(about 100,000 light years or about 30 kpc) across. The Sun does not lie near
the center of our Galaxy. It lies about 8 kpc from the center on what is known
as the Sagittarius arm of the Milky Way.

Explanation:
Answer: Very Likely
Explanation:
Michigan has had 24 deaths from extreme cold in the last 20 years.
This is a rate of:
= 24 / 20
= 1.2 deaths per year.
For something to be considered ''very likely'' to occur, the chances of that thing occurring needs to be above 90%.
Going by the deaths per year, the probability is more than 90% at 120%. It is therefore very likely that there will be a death from extreme cold.
