Which planet is known as earth twin planet?

Venus is often called “Earth’s twin” because both planets are around the same size and density; they are also both rocky planets located in the inner region of the solar system. Yet,Venus couldn’t be less like Earth.It’s the hottest planet in the solar system (even hotter than Mercury, which is closest to the sun), and has temperatures of around 880 degrees Fahrenheit (471 degrees Celsius). That’s hot enough to melt lead. Plus, Venus has quite fearsome surface pressures.Importantly, Venus also lacks a key element for life that’s abundant here on Earth: Water. This is despite the planet being within the so-called “Goldilocks Zone” of the sun, in reference to the region around our star that is neither too hot nor too cold to allow liquid water to exist.
