|When will Jupiter's gravity pull us closer to
outer space? Please answer back this question is

Although Jupiter has a strong gravitational pull
on the earth, it is extremely small compared with
the gravitational pull from the Sun, so we will
never get pulled out of our orbit around the sun
and more towards Jupiter. Gravitational pull
gets stronger with more mass and shorter distance
between two objects, and the sun is over 1000 X
more massive than Jupiter as well as at least 4 X
closer to Earth.
There is really nothing to worry about. Though
earth is much smaller than Jupiter, we are much
closer to the center of the earth than to Jupiter,
so the gravity of the Jupiter barely has any
effect on us. And since the strongest gravity
force on earth is from the sun, so Jupiter will
not pull the earth away from its current orbit.
Jupiter pulls on everything in the earth with
about equal strength, which means that sure, we're
being pulled by Jupiter, but so is the rest of the
earth, so we will go along with the earth. Also,
there are other objects in the solar system
that pull on us much harder than Jupiter - the
sun, for example. Earth has enough forward
motion that it can't fall directly into the sun,
instead falling around it, in an orbit.
Jupiter's gravity: Jupiter is heavy and
indeed exerts the gravitational pull to Earth like
other planets. But also keep in mind, the
gravitational force is inversely proportional to
the distance squared. This could compensate
the heavy mass like Jupiter. It turned out when
Jupiter is closest to the Earth, it will only
slightly affect Earth's orbit around the sun.
