GJ Gliese 273 b Planet

GJ Gliese 273 b Mass Size Compared to Earth in Percentage

The mass of GJ Gliese 273 b is 2.89 times that of Earth. To express this in percentage, we can use the formula: $(\text{Mass of GJ Gliese 273 b}\mathrm{/}\text{Mass of Earth})\times 100$. Plugging in the values, we get $(2.89\mathrm{/}1)\times 100=\mathbf{\text{289\%}}$. Therefore, GJ Gliese 273 b has a mass approximately 289% of Earth's mass.
