摘要：

We report the discovery of 2010 GB(174), a likely new member of the Inner Oort Cloud (IOC). 2010 GB(174) is 1 of 91 trans-Neptunian objects and Centaurs discovered in a 76 deg(2) contiguous region imaged as part of the Next Generation Virgo Cluster Survey (NGVS)-a moderate ecliptic latitude survey reaching a mean limiting magnitude of g' similar or equal to 25.5-using MegaPrime on the 3.6 m Canada-France-Hawaii Telescope. 2010 GB(174) is found to have an orbit with a semi-major axis of a similar or equal to 350.8 AU, an inclination of i similar or equal to 21 degrees.6, and a pericenter of q similar to 48.5 AU. This is the second largest perihelion distance among known solar system objects. Based on the sky coverage and depth of the NGVS, we estimate the number of IOC members with sizes larger than 300 km (H-V <= 6.2 mag) to be similar or equal to 11,000. A comparison of the detection rate from the NGVS and the PDSSS (a characterized survey that "rediscovered" the IOC object Sedna) gives, for an assumed a power-law luminosity function for IOC objects, a slope of alpha similar or equal to 0.7 +/- 0.2. With only two detections in this region this slope estimate is highly uncertain.
