How far we can go to Sun?
How do we know distance to Sun?
The idea of parallax is simple: when objects are observed from two different angles closer objects appear to shift more than do farther ones. … Now knowing the distance between the Earth and the Moon all he needed was the angle between the Moon and Sun at this moment to compute the distance of the Sun itself.
How cold is space?
about -455 degrees Fahrenheit
Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (2.7 kelvin).Sep 25 2020

Will the Sun ever burn out?
Eventually the fuel of the sun – hydrogen – will run out. When this happens the sun will begin to die. But don’t worry this should not happen for about 5 billion years. After the hydrogen runs out there will be a period of 2-3 billion years whereby the sun will go through the phases of star death.

What is the temperature in space?
Hot things move quickly cold things very slowly. If atoms come to a complete stop they are at absolute zero. Space is just above that at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
How much do astronauts get paid?
The pay grades for civilian astronauts are GS-11 through GS-14 based on academic achievements and experience. Currently a GS-11 astronaut starts at $64 724 per year a GS-14 astronaut can earn up to $141 715 in annual salary [source: NASA].
What happens if you jump in space?
You would still die of course but it would be by asphyxiation. Your blood holds enough oxygen for about 15 seconds of brain activity. After that you’d black out with complete brain death following within three minutes.
