The sun is approximately __________ light years from the center of the milky way galaxy
mylen [45]

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.

Conclusion. The plight of refugees. How you feel the refugees should be treated
Zielflug [23.3K]
The plight of refugees is that they suffer deep emotional stresses from displacement. Fleeing their lives in search of a safer place for them to have a future brings with it poverty, fear and health issues. Upon arrival in a new country, I think that they should be treated with equality, dignity and be given the resources and tools from our society to enable them to build a new life for themselves. After their suffering and journey to seek a better place and better life, societies should embrace these people, their skills and abilities and allow them to be a part of other cultures.
