We report the discovery of 2010 GB _ { 174 } , a likely new member of the Inner Oort Cloud ( IOC ) .
2010 GB _ { 174 } is one of 91 Trans Neptunian Objects ( TNOs ) 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 ^ { \prime } \simeq 25.5 — using MegaPrime on the 3.6m Canada France Hawaii Telescope .
2010 GB _ { 174 } is found to have an orbit with semi-major axis a \simeq 350.8 AU , inclination i \simeq 21.6 ^ { \circ } and pericentre q \sim 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 } \leq 6.2 mag ) to be \simeq 11 000 .
A comparison of the detection rate from the NGVS and the PDSSS ( a characterized survey that ‘ re-discovered ’ the IOC object Sedna ) gives , for an assumed a power-law LF for IOC objects , a slope of \alpha \simeq 0.7 \pm 0.2 , with only two detections in this region this slope estimate is highly uncertain .
