can we land on a star??

Answer:
Explanation:
* Polaris is located at a distance of 434 light-years from Earth and has luminosity nearly 4,000 times that of our sun.
* can we land on a star..?
No you simply cant land on the surface of a star. See stars are made of mostly hydrogen and helium. It burns because since it is so massive, the atoms on the inside, under the pressure and gravity from outer layers, start colliding. New elements start forming. During thus process, some mass is lost. This mass is converted into energy by the equation E=MC^2 where c is the speed of light (300000000m/s), m is the mass lost and e is the energy produced. As you can see it is c ^2 i.e. multiplied by a factor of 10000000000000000. So basically it's a burning ball of gas.
The heat energy near the surface of the star is very large. There is no element known which can sustain solid or perhaps even liquid state near this surface. No chance if landing anything there. Let alone human
