1) A Scientist Observed That the Inner System of Our Solar System Ranges Nearly 750 Million Km. This Is Made of Terrestrial Planets and the Asteroid Belt. Scientist Has to Find the Measurement of the Space in the Inner Solar System After the Terrestrial

The total distance of the terrestrial planets from the sun is
57 + 108 + 149 + 228 = 542 million km

So, the remaining space is
750 – 542 = 208 million km

Hence, the remaining space after the terrestrial planets in the inner
solar system is 208 million km.

2) An Astronaut Travelled to Both the Ice Giants. Now, He Has to Find Which One of Them Is Closer to the Sun? Also, He Has to Find the Distance Between the Farthest Ice Giant and Our Earth.

The two ice giants in the solar system are Uranus and Neptune.

Now, 2871 < 4530
So, Uranus is closer to the sun than Neptune.
Also, Neptune is the farthest ice giant from the earth.

The distance of Neptune from the earth is
4530 – 149 = 4381 million km
