We send rockets out of this solar system.

WE do?

You need to get out more.

The Voyager 1 spacecraft is a 722-kilogram robotic space probe of the outer
solar system and beyond, launched September 5, 1977, and currently
operational. It visited Jupiter and Saturn and was the first probe to
provide detailed images of the moons of these planets.

Voyager 1 is the farthest manmade object from Earth, traveling away from
both the Earth and the Sun at a relatively faster speed than any other
probe.[1] Though its sister-craft, Voyager 2, was launched one month
earlier, Voyager 2 will never pass Voyager 1. Neither will the New Horizons
mission to Pluto, despite being launched from Earth at a faster speed than
both Voyager craft, since during its flight Voyager 1 benefited from a
number of gravity assisted speed boosts.[2]

As of May 9, 2008, Voyager 1 is over 15.89 terameters (15.89×1012 meters, or
15.89×109 km, 106.26 AU, 14.72 light-hours, or 9.87 billion miles) from the
Sun, and has thus entered the heliosheath, the termination shock region
between the solar system and interstellar space, a vast area where the Sun's
influence gives way to the other bodies in the galaxy. If Voyager 1 is still
functioning when it finally passes the heliopause, scientists will get their
first direct measurements of the conditions in the interstellar medium. At
this distance, signals from Voyager 1 take more than fourteen hours to reach
its control center at the Jet Propulsion Laboratory, a joint project of NASA
and Caltech in La Cañada, California. Voyager 1 is on a hyperbolic
trajectory and has achieved escape velocity, meaning that its orbit will not
return to the inner solar system. Along with Pioneer 10, Pioneer 11, Voyager
2, and New Horizons, Voyager 1 is an interstellar probe.

Voyager 1 had as its primary targets the planets Jupiter and Saturn and
their associated moons and rings; its current mission is the detection of
the heliopause and particle measurements of solar wind and the interstellar
medium. Both Voyager probes have far outlasted their originally intended
lifespan. Each is powered by three radioisotope thermoelectric generators,
which are now expected to continue to generate enough power to let the
probes keep communicating with Earth until at least the year 2025.
