The ISS is the only habitable artificial satellite in the low-earth orbit and it's a multi-national collaborative project between five participating space agencies NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). In fact, you can track the real-time movement of the ISS on this website. Just register yourself at this website and it will keep alerting you about its movement and when exactly it will pass over your city. US space agency NASA runs a website - Spot The Station - dedicated to tracking the movements of the ISS and tells you the most suitable time to view it in the coming days. The ISS can be sighted from your city in the future. For people living in other cities who will miss this opportunity this time, don't get disheartened. That is the reason that though the ISS can be sighted from these cities on other days of this week too, the view tonight will be the best view possible as it will pass over at nearly 90 degrees angle. The ISS is visible before or after sunrise or sunset. Though the four cities will have the best sighting if clouds are not there, people in nearby cities like Vadodara, Agra and Chandigarh will also be able to sight the ISS but at an angle. ISS will be visible after 8.30 pm - can be sighted for approximately 5-6 minutes at around 8:35 pm in Rajkot and Ahmedabad, and around 8:37 pm in Delhi and Jaipur. Tonight, the ISS will be flying right over these Indian cities at an angle of nearly 90 degrees and give you the perfect opportunity to get a glimpse of the human habitable satellite but only if you have a cloudless sky.

Though not a rare phenomenon, the ISS is easy to spot like a bright star with naked eyes as it is the third brightest object in the sky after the Sun and the Moon, and circles the Earth in roughly 93 minutes, completing 15.5 orbits every day. NEW DELHI: If you live in Delhi, Jaipur, Rajkot or Ahmedabad, you can spot the International Space Station in the sky tonight (Tuesday night).
