If Proxima is 4.3 light years from the sun, how distant is Proxima from the sun in kilometers?

Hint :Proxima may be a small, low-mass star located 4.2465 light-years far away from the Sun within the southern constellation of Centaurus. Its Latin name means the "nearest [star] of Centaurus". This object was discovered in 1915 by Robert Innes and is the nearest-known star to the Sun.

Complete Step By Step Answer:
Proxima Centauri, the closest star to our own, remains 40,208,000,000,000 km away. (Or about 268,770 AU.). Once we mention the distances to the celebs, we do not use the AU, or Astronomical Unit; commonly, the sunshine year is employed.
A light year is that the distance light travels in one year - it's adequate to 9.461 x 1012 km. Alpha Centauri A & B are roughly 4.35 light years far away from us. Proxima is slightly closer at 4.25 light years.
The star Proxima , one among 3 stars within the Alpha Centauri system, is our sun's nearest known neighbor at 4.2 light-years away. Hubble space telescope image of Proxima , the closest known star to the sun.

Note :
Today, the foremost distant objects we will see are quite 30 billion light-years away, despite the very fact that only 13.8 billion years have passed since the large Bang. The farther a galaxy is, the faster it expands far away from us and therefore the more its light appears.
