It seems like 1,000,000,000,000,000 meters away
B Horizon
You can't reach the horizon. No matter where you are or what you do the horizon will always be there in front of you. The distance between the shore and the horizon is infinite.
The horizon. It is a imaginary line where land and sky appear to meet.
It Maybe B horizon or C horizon
Our eyes can only see as far as the horizon, due to the curvature of the Earth. For instance, an observer standing on a hill 100 feet (30 m) in height, their horizon is at a distance of 12.2 miles (19.6 km). Obviously, without the restriction of a horizon, we can look out far into space on a dark night and see our moon and many stars and planets with the naked eye - even better with a telescope.
You can use the phrase "as you can see" to draw attention to something that is easily observable or evident from the information presented. For example, "As you can see from the data chart, there is a clear correlation between temperature and ice cream sales."
That depends on the angle of elevation
