Trappist-1 (2024)

  • Constellation: Aquarius
  • Right Ascension: 23h 06m 29.368s
  • Declination: −05° 02′ 29.04″
  • Distance: 40.6 ly
  • Estimated Age: 7.6 billion years (estimated)
  • Apparent Magnitude: 18.8

Trappist-1 is a red dwarf star located in Aquarius. One tiny red dot located in a sea of dots, it came to fame in 2016-2017 when it was discovered there were seven planets that orbit the star. At around 40 light years distance, it does display a small proper motion across the sky in this sequence of images from 2020 and 2024.

Barnard's Star (2024)

  • Constellation: Ophiuchus
  • Right Ascension: 17h 57m 48.49847s
  • Declination: +04° 41′ 36.1139″
  • Distance: 5.96 ly
  • Apparent Magnitude: 9.5
  • B-V Color Index: 1.713

Barnard's Star is the 4th closest star, and shows the highest proper motion (apparent motion) across the sky. With over 10 arc-seconds of motion per year, the change of its position is visible over a year's time. A small red dwarf, and at magnitude 9.5, it requires optical aid to see it. Also is know as V2500 Oph in the variable star catalogue, as is displayed here.
