Because the Sun is much larger than the Earth.
Black holes have a much higher gravitational attraction than Earth due to their immense mass packed into a small volume, creating a strong gravitational pull that can even trap light.
The moon is much less massive than the Earth, therefore the gravitational attraction of the moon is much weaker (about one sixth).
A force of gravitational attraction exists between earth and every other material body in the universe. But the force of attraction toward the sun is so much larger than any of the others that all others may be approximately neglected in comparison, and there is only one significant force acting on the planet --- the gravitational attraction toward the sun.
It greatly depends upon their distance to one another at the time. However, the universal law of gravitational attraction applies: F = G * ((m1*m2)/r) where m1 is the mass of moon 1 (kg) m2 is the mass of moon 2 (kg) r is the distance (m) G is the gravitational constant F is the force of attraction.
To launch a space shuttle (or anything) you have to overcome gravity. The gravitational attraction of the moon is tremendously less than that of the Earth. The moon is much smaller than the Earth.

Gravitational attraction between Earth and objects is determined by their mass and distance. The more massive an object is, the stronger the attraction. Similarly, the closer an object is to Earth, the stronger the gravitational pull.
A single object doesn't have a gravitational attraction. The gravitational force between two objects is proportional to the product of both of their masses. So the force between the earth and any other object ... like a person ... depends on the mass of the person, just as much as it depends on the earth's mass. You can't tell the strength of the earth's attraction of an object until you know the object's mass. (In other words, you don't know how much a person on earth will weigh until you know something about the person.)
You cannot feel the gravitational attraction between you and an object because the force of gravity is very weak compared to the other forces acting on you (such as electromagnetic forces). Additionally, other factors like the Earth's gravitational field are much stronger, so you are not as sensitive to the gravitational attraction between you and smaller objects.
The force of attraction between the Earth and ourselves is much stronger than the attraction between two apples because the Earth has a much larger mass than an apple and gravitational force is directly proportional to the mass of the objects involved. Additionally, the distance between us and the center of the Earth is much smaller than the distance between two apples, further increasing the gravitational force.
If Earth became much smaller, the force of gravity on its surface would decrease because gravitational force is directly proportional to the mass of the planet. The smaller size would also result in less gravitational attraction between objects on Earth and a weaker gravitational pull overall.
The moon's gravity differential. The sun's gravitational action is much greater, but the difference between its attraction on the close side of the Earth and the far side is much less.
The moon is much less massive than the Earth, therefore the gravitational attraction of the moon is much weaker (about one sixth).

But the force of attraction toward the sun is so much larger than any of the others that all others may be approximately neglected in comparison, and there is only one significant force acting on the planet --- the gravitational attraction toward the sun.
You would weigh more on Jupiter than on Earth because Jupiter has a much larger mass than Earth, resulting in a stronger gravitational pull. This increased gravitational pull would make you feel heavier on Jupiter compared to Earth.
