观看今晚和明天的网络直播中金星和木星的接近

Watch Venus and Jupiter come close to each other tonight and tomorrow in live webcasts

2023年3月1日和3月2日,金星和木星将在夜空中非常接近。

本周,你可以足不出户地观看两颗明亮的行星在天空中并肩闪耀。

在线虚拟望远镜项目将广播我们天空中最亮的两颗行星——金星和木星,当它们在夜空中相距仅半度时。(你紧握的拳头与手臂保持一定距离,覆盖了大约10度的天空。)

如果天气允许,广播将于美国东部时间周三(3月1日)和周四(3月2日)下午1:30(格林尼治标准时间1830)开始。我们将在这两天在太空网上播放流媒体,这得益于该项目的网站(在新标签中打开)。

虚拟望远镜创始人吉安卢卡·马西在活动的网页上写道:“金星和木星的会合总是壮观的:在月亮之后,它们是夜空中最亮的物体。”。

位于意大利的虚拟望远镜在小行星2023BU最接近地球前不久捕捉到了它。

从地球的角度来看,金星和木星已经慢慢地相互侵占了好几个星期;例如,在二月初,它们在天空中相距大约30度。

从我们的角度来看,行星彼此靠近经过是很常见的,尽管无论你多久看到一次,这种情况都很常见。主要行星、月球和太阳都沿着地球天空中一条被称为黄道的假想线移动。这是因为我们太阳系的平面相对平坦,大多数较大的物体相对于太阳倾斜的角度几乎相同。

Venus and Jupiter will be very close to each other in the night sky on March 1 and March 2, 2023.

You can watch two brilliant planets shining beside each other in the sky this week without leaving your home.

The online Virtual Telescope project will broadcast the two brightest planets in our sky  Venus and Jupiter when they are just half a degree apart in the night sky. (Your clenched fist held at arm's length covers about 10 degrees of sky.) 

The broadcast starts, weather permitting, at 1:30 (p.m.) EST (1830 GMT) on both Wednesday (March 1) and Thursday (March 2). We will carry the streams here at Space.com on both days, courtesy of the project's website (opens in new tab).

"A conjunction involving planets Venus and Jupiter is always spectacular: after the moon, they are the brightest objects in the night sky," Virtual Telescope founder Gianluca Masi wrote on the event's webpage (opens in new tab). The planets will be visible from Rome, where he's streaming from, shortly after sunset, Masi added.

The Italy-based Virtual Telescope captured asteroid 2023 BU shortly before its closest approach to Earth.

Venus and Jupiter have been slowly encroaching on each other from Earth's point of view for weeks; for example, at the beginning of February they were roughly 30 degrees apart in the sky.

It's common for planets to pass close to each other from our perspective, although the event is pretty no matter how often you see it. The major planets, the moon and the sun all move along an imaginary line in Earth's sky known as the ecliptic. That's because the plane of our solar system is relatively flat, and most larger objects are tilted to almost the same number of degrees to our sun.
