What is the designation of the newly discovered asteroid mentioned in the article?

The asteroid is designated 2025 SC79 and is described in the report as a twilight asteroid, a body discovered while near the sun’s glare. This naming underscores the unusual conditions under which it was detected and the challenges astronomers face in finding such objects.

How was the asteroid obscured before discovery?

Before it was found, the asteroid remained hidden behind the sun’s glare, making it effectively invisible to most telescopes. Only when an astronomer directed the Dark Energy Camera toward a region near the sun was the object revealed, highlighting how glare can hide potentially hazardous bodies from routine observations.

Which instrument helped discover the asteroid?

The discovery was enabled by the Dark Energy Camera, a powerful instrument used by astronomers to survey the sky. By pointing this camera at a region obscured by sunlight, researchers captured data that led to identifying the new object now classified as 2025 SC79.

How is the asteroid described in terms of size and speed?

It is described as skyscraper-size and moving at a near-record pace for asteroids, illustrating the combination of large size and unusually high velocity that makes it noteworthy. The description also underscores how such bodies can elude detection until specialized observations near the sun reveal them.

What broader implication does the discovery suggest?

The report notes that the discovery highlights the potential dangers of unseen asteroids lurking in the sun's glare. By showing that a massive object can be hidden close to the Sun and still be moving rapidly, it stresses the importance of advancing detection techniques and sustained monitoring to identify such bodies before they become a risk.

文章中提到的新发现的小行星编号是什么？

该小行星编号为 2025 SC79，并在报告中被描述为一颗“黄昏小行星”（twilight asteroid），即在太阳强光附近发现的天体。这一命名强调了它被探测到时所处的特殊环境，以及天文学家在寻找此类天体时面临的挑战。

在被发现之前，这颗小行星是如何被遮挡的？

在被发现之前，该小行星一直隐藏在太阳的强光背后，这使得它对于大多数望远镜来说实际上是不可见的。直到一位天文学家将暗能量相机（Dark Energy Camera）对准靠近太阳的区域时，该天体才显露出来，这凸显了强光如何使潜在危险天体避开常规观测。

哪种仪器帮助发现了这颗小行星？

这一发现是由暗能量相机（Dark Energy Camera）实现的，这是天文学家用来巡天的强大仪器。通过将该相机对准被阳光遮挡的区域，研究人员捕获了相关数据，从而识别出了这颗现在被分类为 2025 SC79 的新天体。

如何描述该小行星的大小和速度？

它被描述为摩天大楼般大小，且移动速度接近小行星的最高纪录，这体现了其巨大的尺寸和异常的高速，使其备受关注。这一描述还强调了此类天体在太阳附近的专门观测揭示它们之前，是如何避开探测的。

这一发现暗示了哪些更广泛的影响？

报告指出，这一发现凸显了潜伏在太阳强光中未被发现的小行星的潜在危险。通过证明一个巨大的天体可以隐藏在靠近太阳的地方且仍在快速移动，它强调了改进探测技术和进行持续监测的重要性，以便在这些天体构成风险之前识别它们。
