If it is visible with the naked eye, why did it take so long to find?

The star is visible with the naked eye, not the planet.

V 3.50

Visual magnitude 3.5. Again, that's the star, not the planet. The planet was found with the doppler technique, it wasn't even seen by telescopes directly.

The planets are so dim the only way to see them is with an Array of Space telescopes like the Hubble.

Once we have an Interferometry Array setup we will be finding all the nearby planets and getting images of them.

are you sure?

The HARPS spectrograph mounted on the ESO/3.6-m La
Silla telescope is yielding a rich bounty of information regarding planets around M dwarfs (eg., Bonfils et al. 2011).
There is a lot of interest in searches for planets about low
mass M dwarfs.

The fun thing about relativity is that it feels like you're travelling faster than light at relativistic speeds. It's not till you look at a clock back on earth that you realize how much time passed... As in years. Planet on the apes (the first one) really captured the essence of that. As for actually travelling faster than light, it may be possible to cheat by warping space, but there's always a catch. All those cosmic rays between you and the destination have to go somewhere...

You are right: not MISinterpreting - just a lack of reading comprehension.
If the one is more idiotic than the other is up to you.

Scientists have discovered a ‘habitable’ planet that orbits a sun visible to the naked eye.

The world is just 12 light years away, is between two and six times bigger than the earth, and is thought to be circling Tau Ceti, a star almost identical to our sun.

The planet is one of five orbiting Tau Ceti, and lies within the star's habitable zone. It is thought to have five times the Earth's mass.

Also known as the “Goldilocks zone”, the habitable zone is the orbital region that is neither too hot nor too cold to allow liquid surface water and, potentially, life.

This is the full article and the link.

 Quoting: BadMoonRising 4583236


Like Astromut said, the planet's not visible (No planet is, because they're too small and way too dim.) We find these by measuring the tug the planet has on it's star as it orbits. We're just getting better at this, and are launching satalites to measure more accurately how the stars are affected.
 Quoting: Anonymous Coward 9266723



Inaccurate. At least 5% of the extrasolar planets are directly imaged. Furthermore, it's not a problem of size: "planets are extremely faint light sources compared to stars and what little light comes from them tends to be lost in the glare from their parent star"
