XRISM
XRISM is a satellite from Japan, launched on September 6, 2023 from Tanegashima, Japan. It is in a low orbit, 520 to 531 km above the ground, and goes around the Earth every 95.1 minutes: 15.1 times a day, at 7.60 km/s (27,400 km/h).
Where XRISM is right now
The gold ring is its orbit, and the line drops to the point on the ground under it. Inside the white circle it is above the horizon. Drag the globe to turn it, pinch or use the buttons to come closer; the target button brings you back to the satellite. The 2D map shows its path over the ground for the next lap: gold where it is in sunlight, dashed where it is in Earth’s shadow.

About XRISM
An X-ray telescope from Japan’s space agency with NASA and the European Space Agency, launched in September 2023. It measures the X-rays from the hot gas in clusters of galaxies and around black holes precisely enough to tell what the gas is made of and how fast it is moving.
Can you see it?
From where
It passes straight overhead only between latitudes 31° north and 31° south, and rises above the horizon as far as about 53°. Nearer the poles than that it is never in the sky.
A satellite shows only when your sky is dark and it is still in sunlight: in the hours after dusk and before dawn.
When it passes over you
The app works out its passes over your exact location, alerts you before one, and leads you to it with an arrow in the camera view.

Quick answers
Where is XRISM right now?
The map on this page shows where XRISM is at this moment, the path it will follow over the ground for the next lap, and the part of the Earth it is above the horizon for. It is worked out from the latest tracking data.
How high is XRISM?
Between 520 km at its lowest and 531 km at its highest, above the ground.
How fast does XRISM go?
About 7.60 km/s, which is 27,400 km/h. One lap of the Earth takes it 95.1 minutes, so it goes around 15.1 times a day.
Can you see XRISM without a telescope?
No brightness estimate. We have no brightness estimate for it, so we cannot say how easy it is to see.
When was XRISM launched?
On September 6, 2023, from Tanegashima, Japan.
With the app
Knowing where it is over the Earth is one thing. The app shows you where it is in your sky.
This page follows the satellite around the planet. The app works out when it passes over you, and leads you to it.
- Every pass over your exact location, for this satellite and 10,000+ more.
- An alert before it rises, so you are outside in time.
- An arrow in the camera view that leads you to the exact spot in the sky.
