鸟神星(听起来像MAH-kay MAH-kay)是柯伊伯带第二亮的矮行星,有一颗卫星。它的昵称是MK2,反射阳光的表面呈炭黑色,比其母星暗淡约1300倍。尽管如此,2016年,它还是在哈勃太空望远镜的观测中被发现,哈勃太空望远镜试图用与发现冥王星小卫星相同的技术来寻找微弱的伴星。就像对冥王星及其卫星一样,对造神星及其轨道卫星的进一步观测将测量该系统的质量和密度,从而对遥远的世界有更广泛的了解。MK2的直径约为160公里(100英里),而Makemake的直径为1400公里,MK2的相对大小和对比度显示在这位艺术家的视野中。这是一幅想象中的未开发的太阳系边界的场景,它从宇宙飞船的有利位置向后看,昏暗的太阳沿着银河系闪耀。当然,太阳到造神星的距离是它到地球的距离的50多倍。

Makemake (sounds like MAH-kay MAH-kay), second brightest dwarf planet of the Kuiper belt, has a moon. Nicknamed MK2, Makemake's moon reflects sunlight with a charcoal-dark surface, about 1,300 times fainter than its parent body. Still, in 2016 it was spotted in Hubble Space Telescope observations intended to search for faint companions with the same technique used to find the small satellites of Pluto. Just as for Pluto and its satellites, further observations of Makemake and orbiting moon will measure the system's mass and density and allow a broader understanding of the distant worlds. About 160 kilometers (100 miles) across compared to Makemake's 1,400 kilometer diameter, MK2's relative size and contrast are shown in this artist's vision. An imagined scene of an unexplored frontier of the Solar System, it looks back from a spacecraft's vantage as the dim Sun shines along the Milky Way. Of course, the Sun is over 50 times farther from Makemake than it is from planet Earth.
