i need info about it it can be anything about the solarsystem i need at least some info about something.
If you go to wikipedia.com and search on "solar system", you will find a lot of useful information about the solar system, the sun itself, the planets, moons and other objects.

Our solar system contains one star – the sun.
There are four inner rocky planets (Mercury, Venus, Earth and Mars) and four outer gaseous planets (Jupiter, Saturn, Uranus and Neptune).
Pluto has recently been reclassified and is no longer considered to be a planet.
Our solar system is the only one known to contain life.

Our solar system consists of an average star we call the Sun, the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. It includes: the satellites of the planets; numerous comets, asteroids, and meteoroids; and the interplanetary medium. The Sun is the richest source of electromagnetic energy (mostly in the form of heat and light) in the solar system. The Sun’s nearest known stellar neighbor is a red dwarf star called Proxima Centauri, at a distance of 4.3 light years away. The whole solar system, together with the local stars visible on a clear night, orbits the center of our home galaxy, a spiral disk of 200 billion stars we call the Milky Way. The Milky Way has two small galaxies orbiting it nearby, which are visible from the southern hemisphere. They are called the Large Magellanic Cloud and the Small Magellanic Cloud. The nearest large galaxy is the Andromeda Galaxy. It is a spiral galaxy like the Milky Way but is 4 times as massive and is 2 million light years away. Our galaxy, one of billions of galaxies known, is traveling through intergalactic space.
The planets, most of the satellites of the planets and the asteroids revolve around the Sun in the same direction, in nearly circular orbits. When looking down from above the Sun’s north pole, the planets orbit in a counter-clockwise direction. The planets orbit the Sun in or near the same plane, called the ecliptic. Pluto is a special case in that its orbit is the most highly inclined (18 degrees) and the most highly elliptical of all the planets. Because of this, for part of its orbit, Pluto is closer to the Sun than is Neptune. The axis of rotation for most of the planets is nearly perpendicular to the ecliptic. The exceptions are Uranus and Pluto, which are tipped on their sides.

Well, there are 8 planets, along with at least 4 ‘dwarf’ planets. The largest object is the sun – 1.3 million Earths could fit inside it. Mercury is the closest planet to the sun, orbiting in just 88 days. Mercury’s just a little larger than our moon, and they look a lot alike – many impact craters. Next is Venus, it’s about the size of Earth – just a little smaller. It’s orbital period is about 264 days. There’s the Earth – we’re 93,000,000 miles away from the sun, and we take 365 days to orbit.
Mars is next, it’s about 1/2 the size of the Earth, and has 2 moons, phobos & deimos – which aren’t round, they look like potatos…. They’re probably captured asteroids.
Next is Jupiter – it’s diameter is 11 times larger than Earths – we’re 8,000 miles across, Jupiter is about 88,000 miles in diameter. It has at least 37 moons, and a very faint ring. It circles the sun about every 11 years.
Saturn is next, 2nd largest planet and most known for the rings that circle it. It has at least 57 moons, not counting the bits of rock & ice in the rings. it takes 29 years for Saturn to go around the sun once.
Uranus is next, with about 9 moons. All the planets rotate, more or less, in the same plane as their orbit – except this one. Uranus was knocked on it’s side at some point, probably when a huge planet-mass collided with it.
The farthest, true planet is Neptune – with 5 moons. Triton, it’s largest moon, is probably the coldest moon in the whole solar system.
Then, there’s Pluto… a dwarf planet. It has at least 3 moons, two are very small & dark, the largest one is about 1/3 of Pluto’s size. Pluto takes 284 years to orbit the sun, and it’s orbit cuts inside that of Neptune. From 1995 to about 2006, it was *closer* to the sun than Neptune was.
Uranus is next -
