The planet orbiting epsilon Eridani is a giant planet, with a mass about 1.5 times that of Jupiter.
带有行星的epsilonEridani是一颗巨行星,质量为木星的1.5倍。
Times epsilon as the scaling factor.
乘以ε作为比例系数。
Formally, if s(p)gives the quantity supplied for each price p, the elasticity of supply, denoted h (the Greek letter 「eta」, chosen because epsilon was already taken) is
There is an unconfirmed detection of another planet in the epsilon Eri system, also a giant planet (although less massive at 0.1 Jupiter masses) in a very distant (40 AU) orbit.
