Wobbling, transit methods can only find large planets,..Directs observation is also difficult..When planet isvfar away the periods are very long and difficult to watch with the present day technology..
The primodial Universe only had hydrogen and helium. There were no elements for making solid things like earth-like planets, when the first stars formed.
As with anything orbiting around body, the smaller the orbit the faster the object travels. Particles in an accretion disc around a large star will be travelling relatively slowly Particles...
When you are dealing with solar units, the luminosity-radius-temperature relationship is simplified to: $=>L = R^2T^4$ Solving for $R$: $=>R = sqrtL/T^2 $ We are given $T =...
Our solar system is moving along with the galaxy of course. It is also moving, though rather slowing, within the galaxy. We do not have a good grasp of other...
around 5 probes are in orbit around mars.Maven, Mangal yan, mars orbiter Mars oddessy. etc. THewy are in working condition. Another 8 are in orbit but lost contact or control.
Now both ground based and space based telescope shave found out about 3577 Exo plantes around other stars. Few rogue planets were also found orbiting the galaxy with out stars.
Our Sun was formed by a rotating cloud of dust and gas called a Nebula mainly due to a nearby gravitational event that collapsed the nebula, more and more matter...
