太阳是好星球还是坏星球（TheSuns）After the research team carried out simulations to trace the origins of the mysterious asteroid they discovered that BZ has been in our Solar System for around 4.5 billion years. Though its origins are still unknown BZ’s discovery as the first permanent asteroid immigrant can offer clues into our own Sun’s original star nursery and its environment. 该报告的主要作者法特·纳穆尼博士说：“如果2015年的BZ509是我们这个系统的原生行星，那么
Our Solar System has grown up with an asteroid we never knew came from another system until now。
我们的太阳系是在一颗我们从未知道来自另一个星系的小行星上成长起来的，直到今天
A new study has revealed that an asteroid co-orbiting with Jupiter is the first to be identified as a permanent interstellar immigrant from another solar system. The asteroid named (514107) 2015 BZ509 or BZ for short stood out among its asteroid neighbours for its strange orbiting behaviour. The majority of objects in our Solar System orbit the Sun in the same direction. BZ however defies convention and travels in the opposite direction in what’s known as a retrograde orbit.
一项新的研究显示，一颗与木星同轨道运行的小行星，是第一个被确认为来自另一个太阳系的永久星际移民。这颗小行星被命名为（514107）2015 BZ509（简称BZ509），以其奇怪的轨道行为而在其小行星邻居中脱颖而出。我们太阳系中的大多数天体都以同样的方向绕太阳运行。然而，BZ却违背常规，在所谓的逆行轨道上朝着相反的方向行进。
Rather than just being a rocky rebel this orbital defiance is an indication that BZ was born in a galaxy far far away.
与其说它是一个多岩石的反叛者，这种轨道上的违抗是一个信号，表明BZ出生在一个遥远的星系。
“If 2015 BZ509 were a native of our system it should have had the same original direction as all of the other planets and asteroids inherited from the cloud of gas and dust that formed them ” said lead author Dr Fathi Namouni.
该报告的主要作者法特·纳穆尼博士说：“如果2015年的BZ509是我们这个系统的原生行星，那么它就应该和形成它们的气体和尘埃云中继承的所有其他行星和小行星具有相同的方向。”

在研究小组进行了追踪这颗神秘小行星起源的模拟之后，他们发现BZ已经在我们太阳系中存在了大约45亿年。虽然它的起源仍然未知，但BZ的发现作为第一个永久小行星移民，可以以我们自己的太阳的原始恒星托儿所和它的环境提供线索，。
