Us­ing NASA’s Spitzer Space Tel­e­scope, the team of as­tro­no­mers found an iden­ti­cal as­ter­oid belt or­bit­ing Ep­si­lon Erid­a­ni at a si­m­i­lar dis­tance. They al­so found a sec­ond as­ter­oid belt about sev­en times fur­ther off, about the equiv­a­lent of where Ura­nus lies in our so­lar sys­tem. The sec­ond as­ter­oid belt is be­lieved to con­tain about as much mass as our Moon.
