Here's why:
* Newton's Law of Universal Gravitation: This law states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
* F = G * (m1 * m2) / r²
* F = Force of gravity
* G = Gravitational constant
* m1 = Mass of the star
* m2 = Mass of the planet
* r = Distance between their centers
* Doubling the Star's Mass: If we double m1 (the star's mass), the force of gravity (F) will also double, assuming the distance (r) and the planet's mass (m2) remain constant.
In simpler terms: A more massive star exerts a stronger gravitational pull on its planet.
