What is the name of a planet very similar to our Earth?

The planet that is very similar to Earth is Venus. It is similar to Earth in its atmosphere. Of course there are other planets that are similar to Earth, but I think this planet is Venus.
Alternative Earth has become the most talked about topic on the Internet today. NASA scientists have discovered a planet that is very similar to ours. A year there lasts only 20 days longer than on Earth. And the star around which Kepler-452b orbits is almost identical to the Sun. These facts inspired some bloggers so much that they are already talking about possible colonization, even though it takes more than half a million Earth years to fly to the “second Earth”.
