本月的黎明时分都可看到5颗行星按序排列

Five planets — Mercury, Venus, Mars, Jupiter and Saturn — will be sequentially aligned and visible at dawn throughout this month. These planets were last lined up in sequential order in 2004, and it's set to happen again in 2040. If you want to take a gander, be sure to be at your viewing spot about 30 minutes before sunrise.
