Planets not orbiting a star but instead orbiting the galactic center are referred to as rogue planets, or nomadic or interstellar planets.
Voyager 1 and 2 visited the outer planets and went on into interstellar space.
The word 'interstellar' in a sentence: The interstellar nebula was huge compared to the asteroid.
Gravity keeps planets in orbit around the sun. If planets were not subject to the gravitational attraction of the sun, they would fly off into interstellar space. In addition, gravity is also what holds planets together. If there were no gravity, the planets, and the sun, would disintegrate under the force of their own spin. There would be nothing left of the solar system but an expanding cloud of gas and dust.
Planetesimal formation.

It isn't completely clear what you mean with "interstellar aliens": aliens on planets surrounding other stars, or aliens capable of interstellar travel? In any case, it is currently unknown whether ANY life exists in other places of the Universe; whether it is aliens capable of interstellar travel, or even just bacteria on other planets. It seems likely, given the huge amount of planets in the Universe, that there is life somewhere else than Earth - but this hasn't been confirmed yet.
Yes. Without the sun's gravity the planets would move out into interstellar space in straight lines.

Black holes, stars, planets, proto-planets, large and small agglomerates (comets, meteors, interstellar dust), gas clouds.
The force of gravity keeps the planets in their orbits, and without it they would all go off in straight lines into interstellar space.

Things that the Voyagers both did was take pictures of gas planets and record sounds from them planets as they orbited them. Now the Voyager 1 heads to the interstellar space while the voyager 2 does work on the outer solar system.
The Vulcans are a fictional species from the planet Vulcan in the Star Trek universe. Vulcan is part of the United Federation of Planets, a fictional interstellar alliance.
These are known as interstellar probes, a space probe that has left, or is expected to leave the solar system and enter interstellar space. There are currently five out there; Pioneer 10 (now inactive), Pioneer 11 (inactive), Voyager 1 (functional), Voyager 2 (functional) and New Horizons (functional - currently on its way to Pluto). There are, or have been various other interstellar probes in the pipeline, including; `TAU mission` (a probe designed to reach a thousand astronomical units in 50 years), the `Innovative Interstellar Explorer` and the `Realistic Interstellar Explorer & Interstellar Explorer`.
Interstellar dust grains typically range in size from a few nanometers to hundreds of nanometers. They are composed of various materials such as silicates, carbonaceous material, and ices, and play a crucial role in the formation of planets and stars in space.
