Activity is an indicator (*) that appears on a specific planet or moon.

Activity on is triggered by two main categories of events:

• Logging In: Triggers activity on the planet/moon the player logs into.
• Clicking Menus: Clicking almost any menu (Overview, Fleet, Defense, Research, etc.) triggers activity on the currently selected planet or moon.
• Clicking Empire menu: Creates activity on every planet
• Refreshing the Page: Updates the activity on the active planet/moon.
• Using Sensor Phalanx: Triggers activity on the moon from which the Phalanx was scanned, but it does not create activity on the target planet being scanned.

• Fleet Arrivals: Any fleet arriving at a planet or moon (yours, an ally's, or an enemy's) triggers activity on that target destination except hold missions.
• Espionage: An enemy espionage probe arriving at a planet/moon triggers activity on it.
• Fleet Returns: A fleet returning to its origin point triggers activity upon landing.
• Build completion: If the buildings are scheduled in the build queue, the game refreshes on completion

When you view the Galaxy screen, activity is displayed directly next to the planet or moon's image. The indicators follow a strict timeline based on the last triggered event:

If a planet or moon has no activity indicator, it simply means no clicks have been made on that specific planet/moon, and no fleets have landed there in the last 60 minutes.

However, you must be careful: No activity does not guarantee the player is offline. Because activity is localized, a player could be sitting online, actively building ships and sending fleets from „Planet A,“ while „Planet B“ shows completely dead with no activity. Advanced players often sit on a moon without clicking to lure in attackers, or they only refresh a single planet to hide the fact that they are online.

• Buddy List: If the player is on your buddy list, you can see their overall account activity.
• Statistics Page: While it doesn't show an activity star, players watching the Highscores can track if a player's points are updating, which is a secondary way to confirm if an „inactive-looking“ player is actually online and spending resources.

Players are marked as inactive if they remain inactive for:

1. more than 7 days, which is indicated by an (i) next to the player's name
2. more than 28 days, which is indicated by an (I) next to the player's name
3. By default, an account is deleted after 42 days, but this may vary depending on the universe settings.

When the inactivity period begins, newbie protection and strong player status are removed.
