Answer: 4.5 light years
Example;Lets say that in the dinosaur days there was a star that exploded.
after 8 light years we would see it now. (now as in 2020) So thats why 4.5
light years is more then 150 million kilometers.
The geographic use of technology to view and record observations from a distance is known as remote sensing.
It replaces slower, steeply-priced statistics series at the ground, presenting rapid and repetitive coverage of extraordinarily huge areas for everyday programs, ranging from weather forecasts to reviews on herbal failures or climate change.
Remote sensing is the manner of detecting and tracking the physical characteristics of a place by using measuring its meditated and emitted radiation at a distance (commonly from a satellite or plane). special cameras gather remotely sensed photographs, which help researchers "experience" matters approximately the Earth.
Examples of passive far-flung sensors consist of film pictures, infrared, charge-coupled gadgets, and radiometers. active series, on the other hand, emits energy in order to experiment with objects and areas whereupon a sensor then detects and measures the radiation that is meditated or backscattered from the goal.

Answer:
Russia has built the Trans-Siberian Railroad to overcome the Friction of Space.
Explanation:
Russia is the largest country in the world, and on top of it, its territory is stretched by longitude which creates a situation where from the easternmost to westernmost point the distance is incredibly big. As both the eastern and western coasts are strategically very important for Russia, it is crucial that they are connected with infrastructure that will enable relatively fast and cheap transportation and traveling.
The solution came in the form of the Trans-Siberian Railroad. This is the longest railroad in the world, starting from Saint Petersburg, diverging into two lines, one going to Tyumen but before that at Yekaterinburg turning to merge with the other line at Chelyabinsk, continuing to Chita where it diverges again with one line going through Khabarovsk to Vladivostok while the other moving slightly through Mongolia, Harbin in China, and ending in Vladivostok.
The correct answer is true
