Simulations suggest that the inner part of the habitable zone of 47 Ursae Majoris could host a terrestrial planet in a stable orbit , though the outer regions of the habitable zone would be disrupted by the gravitational influence of the planet 47 UMa b. However , the presence of a giant planet within 2.5 AU of the star may have disrupted planet formation in the inner system , and reduced the amount of water delivered to inner planets during accretion . This may mean any terrestrial planets orbiting in the habitable zone of 47 Ursae Majoris are likely to be small and dry . , there have been two METI messages sent to 47 Ursae Majoris . Both were transmitted from Eurasia 's largest radar — 70-meter ( 230-foot ) Eupatoria Planetary Radar . The first message , the Teen Age Message , was sent on September 3 , 2001 , and it will arrive at 47 Ursae Majoris in July 2047 . The second message , Cosmic Call 2 , was sent on July 6 , 2003 , and it will arrive at 47 Ursae Majoris in May 2049
