Surface height variations over the entire equatorial region on Venus have been estimated from extended series of measurements of interplanetary radar echo delays. Most notable is a mountainous section of about 3-kilometer peak height located at a longitude of 100 degrees (International Astronomical Union coordinate system). The eastern edge has an average inclination of about 0.5 degrees, which is unusually steep for a large-scale slope on Venus. The resolution of the radar measurements along the surface of Venus varied between about 200 and 400 kilometers with a repeatability in altitude determination generally between 200 and 500 meters. The mean equatorial radius was found to be 6050.0+/-0.5 kilometers.
已从行星际雷达回波延迟的扩展测量系列中估算出金星整个赤道地区的表面高度变化。最显著的是一个约 3 公里高峰高度的山区，位于经度 100 度（国际天文学联合会坐标系统）。东侧的平均坡度约为 0.5 度，对于金星这样的大规模斜坡来说，这是异常陡峭的。金星表面的雷达测量分辨率在 200 至 400 公里之间变化，高度测定的重复性通常在 200 至 500 米之间。平均赤道半径为 6050.0+/-0.5 公里。
